RADICAL POLYMERIZABLE RESIN COMPOSITION AND STRUCTURE REPAIRING MATERIAL
Provided are a radical-polymerizable resin composition and a structure repairing material which, when used for repairing concrete structures, enable construction working even in a low-temperature environment, achieve a high strength and a low shrinkage by curing, and prevent cracking. The radical-polymerizable resin composition contains a radical-polymerizable resin (A) containing at least one selected from the group consisting of a vinyl ester resin, an urethane (meth)acrylate resin, and a polyester (meth)acrylate resin, a radical-polymerizable monomer (B) containing an isobornyl group-having unsaturated compound (B1), and a hydroxy group-containing aromatic tertiary amine (C) represented by the general formula (I), and containing the radical-polymerizable resin (A) and the radical-polymerizable monomer (B) in a total amount of 75% by mass or more. The structure repairing material contains the radical-polymerizable resin composition, an organic peroxide, and a filler (Z).

Polylactic acid (PLA) with low moisture vapor transmission rates by grafting through of hydrophobic polymers directly to PLA backbone
Polylactic acid-backbone graft and bottlebrush copolymers with low moisture vapor transmission rates are synthesized by polymerizing a lactide-functionalized hydrophobic macromonomer using ring-opening polymerization (ROP). In some embodiments of the present invention, the macromonomer is a lactide-functionalized hydrophobic polymer that may be synthesized by, for example, polymerizing a hydrophobic monomer (e.g., a fluorinated vinyl monomer such as 2,2,2-trifluroethyl methacrylate) capable of undergoing radical polymerization (e.g., styrenic, vinylic, acrylic, etc.) using a brominated lactide initiator via atom transfer radical polymerization (ATRP). The brominated lactide initiator may be 3-bromo-3,6-dimethyl-1,4-dioxane-2,5-dione prepared by, for example, reacting lactide with N-bromosuccinimide in the presence of benzoyl peroxide.

AEROSOL PAINT COMPOSITION AND METALLIC MECHANICAL PART COATED WITH SAME
Provided are an aerosol coating composition excellent in a matte effect and capable of preventing co-rotation from occurring. The aerosol coating composition contains a modified alkyd resin, inorganic microparticles and an organic solvent. Herein, the modified alkyd resin is a non-aqueous dispersion resin which is a copolymer of a vinyl based monomer and an alkyd resin. The inorganic microparticles are made of one selected from silica, titanium oxide, zinc oxide, alumina, calcium carbonate, talc and clay or the like. The inorganic microparticles have a mean particle diameter of 1.0 to 10.0 μm, and a content of 0.1 to 5 mass %. There is also provided a metallic mechanical part coated with the aerosol coating composition.

DIRECTLY ATTACHING, HALOGEN-FREE, FAST-DRYING, HEAT-SEALING BINDER FOR SEALING POLYESTER FILMS TO POLYSTYRENE, POLYESTER OR PVC
The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.
