MANUFACTURING METHOD OF POLYMER MATERIAL
A manufacturing method of a polymer material at least includes the following steps. A raw material including polyethylene terephthalate is provided. An alcoholysis reaction is performed by using the raw material with aliphatic diols to form an intermediate product, wherein the intermediate product includes bis 2-hydroxyethyl terephthalate. A polymerization reaction is performed by using the intermediate product and polytetramethylene ether glycol to form a thermoplastic polyester elastomer.
Coating system for RMA crosslinkable coating compositions
The invention relates to a coating system comprising a binder composition comprising a polymer having a Mn of 6,000 to 60,000 g/mol, a Mw of 20,000 to 300,000 g/mol, a Tg of 30 to 180? C. and an acid value of at most 3.0 mg KOH/g, and a RMA crosslinkable coating composition comprising a component A with at least two acidic protons CH in activated methylene or methine groups, a component B with at least two activated unsaturated C?C groups and a base crosslinking catalyst C; and its use for improving adhesion of the RMA crosslinkable coating composition, in particular to wood substrates.
LIQUID MODIFIED PET POLYESTERS FOR LITHOGRAPHIC INKS
The present invention is directed to a method of making liquid polyester resins, and the liquid polyester resins produced by the method. The liquid polyester resins are prepared by de-polymerizing virgin, scrap, recycled or reclaimed polyethylene terephthalate (PET) via an alcoholysis reaction with one or more mono-alcohols and/or polyols; transesterifying the resulting polyol oligomer with vegetable oils or fatty acid alkyl esters; and re-polymerizing with acids or anhydrides. The present invention also provides ink and coating compositions, and overprint varnishes, comprising the liquid polyester resins of the invention.
OXIDATIVELY CURABLE COATING COMPOSITION
The present invention relates to an oxidatively curable coating formulation comprising an oxidatively curable alkyd-based resin and a chelant capable of chelating at least one transition metal ion through either three or four nitrogen atoms, which chelants may each optionally be complexed with one or two transition metal ions, typically iron or manganese ions. The formulations may be paints or other oxidatively curable coating compositions. The invention also provides methods for making such formulations and compositions resultant from the curing of such formulations.
RMA CROSSLINKABLE COMPOSITIONS AND RMA CROSSLINKABLE RESINS FOR EASY TO CLEAN COATINGS
The invention relates to RMA crosslinkable coating composition, a method for the preparation thereof and a resulting coating having easy to clean properties useful in applications like graffiti resistant, sanitisable coatings and in flooring, said composition comprising RMA crosslinkable component with at least 2 RMA donor groups and at least 2 RMA acceptor groups characterized by having fatty components selected from the group of fatty acids, fatty alcohols, fatty amines, fatty thiols and dimeric fatty acid in an amount represented by an Oil Content OC between 0, preferably 4 and 40 wt %, and crosslinking density XLD of at least 1.4 a glass transition Tg of at least 290 in combination providing a easy to clean value ?E less than 20.

SYNTHESIS OF ENVIRONMENTALLY DEGRADABLE ALKYL POLYESTERS
A solid crosslinked polyester composition that is environmentally degradable in less than about 180 days. The crosslinked polyester can be the polyesterification reaction product between one or more multi-hydroxylic alcohols, one or more hydroxy acids, and one or more multi-carboxylic acid compounds. Alternately, the crosslinked polyester can be the polyesterification reaction product of one or more multi-hydroxylic alcohols, one or more hydroxy acids, one or more multi-carboxylic acid compounds, and a cyclic ester. Provided, however that if the one or more hydroxy acids has only one carboxyl group, it has two or more hydroxyl groups, and if the one or more hydroxy acids has only one hydroxyl group, it has two or more carboxyl groups.
Resin emulsion composition, and process of obtaining same
The present invention relates to aqueous resin emulsions containing at least a non-ionic surfactant of general formula R.sub.1-(A.sub.1O).sub.n-(A.sub.2O).sub.x-(A.sub.3O).sub.yR.sub.2, obtained by the phase inversion emulsification process. In particular, the invention relates to aqueous resin emulsions commonly used in solvent-based paints, such as, for example, alkyd resins. Said emulsions are stabilized by non-ionic and anionic surfactant compositions which promote the inversion of the water-oil to oil-water phases in the presence of low water content, enabling water-oil type emulsions to be obtained with high productivity and high solids content, even in low shear conditions.
Resin-coated metal sheet for containers
The resin-coated metal sheet for containers includes a resin coating layer (A) having a multilayered structure mainly composed of a polyester resin on at least one surface thereof. The resin coating layer (A) includes a resin layer (a1). The resin layer (a1) adheres to the metal sheet, contains (i) a polyester resin, (ii) a phenolic resin, (iii) a metal alkoxide compound and/or a metal chelate compound, (iv) an epoxy resin, and (v) at least one selected from the group consisting of polyamine resins, polyamidoamine resins, and polyamide resins, and is mainly composed of the polyester resin. Preferably, a polyester film (a2) is disposed on the resin layer (a1).
A Method for Optimizing a Hegman Rating of a Diluted Emulsion, a Diluted Emulsion Produced Thereby, and a Coating Made
A method for optimizing a Hegman rating of a diluted emulsion including adjusting the shear work in the dilution mixer, wherein the adjusting the shear work may comprise raising or lowering the shear work; adjusting the temperature of the concentrated and/or diluted emulsion; if not earlier added, adding a basic aqueous solution and/or dispersing agent; adding one or more other additives; and/or adjusting the amount of any additive, basic solution or surfactant solution is provided.
