Styrenated maleinized fatty acid glyceride copolymer for aqueous dispersed binders in solvent free ambient dry paints




Loading Importance Indicators... loading....


See full text

An ambient dry water dispersed coating composition substantially free of volatile organic coalescing solvents, the coating composition containing a polymer film forming binder comprises between 40% and 50% copolymerized non-conjugated, unsaturated fatty acid triglyceride, between 40% and 55% copolymerized ethylenic monomer including styrene, and between 3% and 12% copolymerized maleic anhydride. The film forming copolymer is produced by first reacting maleic anhydride with the fatty acid triglyceride at high temperatures between C. to form a maleinized triglyceride having a pendent maleic anhydride structure. The maleinized triglyceride is then styrenated at temperatures between about C. and C. in the presence of at least 4% peroxide initiator based on the weight of monomers copolymerized to form a styrenated, maleinized fatty acid triglyceride copolymer having anhydride groups. The anhydride groups are neutralized with amine or ammonia and the neutralized copolymer is dispersed in water.
