This disclosure generally provides tris (hydroxymethyl) phosphine oxide based polyfunctional polyester polyol compounds and resin compositions made therefrom which have improved flammability, wherein the resin composition comprising: (a) a polyfunctional isocyanate; (b) an isocyanate reactive composition comprising (b1) a polyfunctional polyol composition and a catalyst composition; and optionally (b2) a polyfunctional amine; wherein the polyfunctional polyol composition comprises tris (hydroxymethyl) phosphine oxide based polyfunctional polyester polyol compound.

The present invention relates to non-halogenated and non-metal polymerizable flame retardants, their preparation, compositions containing the same and uses thereof. These flame retardants may be polymerized with other ethylenically unsaturated compounds and chemically bound to the resin matrix thus limiting their migration out of the finished product. The flame retardants of the invention are also more environmentally friendly than conventional halogen-based or metal-based flame retardants.

Flame retardant polyesters obtainable by reacting an aromatic or aliphatic dicarboxylic acid and/or ester of anhydride thereof, with an aliphatic polyol or mixtures thereof and with melamine, are provided. Methods of making said polyesters are also provided.

The present disclosure provides a two-component solvent-less adhesive composition. The two-component solvent-less adhesive composition contains the reaction product of (A) an isocyanate component; and (B) a polyol component containing (i) a polyester-polycarbonate polyol and (ii) a phosphate-terminated polyol. The present disclosure also provides a method of forming the two-component solvent-less adhesive composition.

The invention provides a carbon dioxide-based polyurethane elastomer with damping and anti-fatigue aging properties and its preparation method. It is obtained from Component A and Component B; Component A includes: PTMG-1000 4560 parts, carbon dioxide-based polyol 2530 parts, poly-DOPO-ITA-pentanediol ester 1020 parts, BDO 35 parts, water 0.30.5 parts, N-methylimidazole 0.50.8 parts, bis(2-dimethylaminoethyl) ether 0.10.2 parts, needle-shaped nano-titanium dioxide 0.5 parts, hindered phenol 0.20.5 parts, dibutyltin dilaurate 0.10.3 parts, strontium chloride 0.0050.01 parts, rhodium chloride 0.020.03 parts, foaming agent 0.20.5 parts; Component B includes: carbon dioxide-based polyol 5055 parts, MDI-50 4550 parts, organic zinc 0.010.02 parts, organic bismuth 0.010.02 parts.

A solvent based retort adhesive comprising at least one isocyanate component comprising a blend of at least one aromatic based isocyanate with free monomeric isocyanate of less than 1 wt. % and at least one aliphatic-based isocyanate, and at least one NCO reactive component comprising a phosphate ester polyol and at least one polyester polyol having a molecular weight of at least 2,000 g/mol is disclosed. A process for producing the adhesive along a laminate partially comprising the adhesive and a process for producing the laminate is also disclosed.

Provided is a process for preparing a zipper pouch, wherein the process comprises: A) forming a first laminate by a process comprising i) bringing together a polyisocyanate component and a polyol component to form an adhesive composition, ii) applying a layer of the adhesive composition to a layer of polyethylene terephthalate, iii) then contacting the layer of the adhesive composition with a layer of polyethylene having thickness of 80 micrometer or more; B) contacting a polymeric zipper construction to the first laminate at temperature of 200 C or higher. Also provided is a zipper pouch made by that process.
