Abstract: PURPOSE:To obtain a coating material, preventing the migration of a plasticizer and an additive and eliminating contamination of a product, etc., when applied to an agricultural PVC film, by adding a specified compound into an aqueous dispersion of a (meth)acrylate (co)polymer. CONSTITUTION:2-40wt% of a compound of a the formula (wherein R is CH3 or C2H5; n is 2 or 3) is added into an aqueous dispersion of a polymer obtained by the (co)polymerization of a (meth)acrylate monomer or the copolymerization of said monomer with a copolymerizable vinyl monomer. When a coat is formed by the application of the material obtained to a soft or semisoft vinyl chloride film, the plasticizer or an additive is prevented from migration, and defect such as contamination of the product or sticking is eliminated.

Abstract: PURPOSE:To obtain both novel polyamic acid and polyimide with high heat resistance, transparency and solubility in solvent, by the polymerization between aminobenzylamine and tetracarboxylic dianhydride. CONSTITUTION:The objective polymer having recurring unit of formula -X-Y-[X is of formula I ; Y is of formula II (R is >=C2 tetravalent organic group) or III]can be obtained by the polymerization, in an organic polar solvent (optimally N-methyl-2-pyrrolidone) pref. at

Abstract: PURPOSE:To obtain both novel polyamic acid and polyimide of high heat resistance transparency and processability, with good balance in these propenties, by the reaction between aminobenzylamine and tetracarboxylic dianhydride. CONSTITUTION:(A) An aminobenzylamine (pref. m-aminobenzylamine) and (B) tetracarboxylic dianhydride of formula I (e.g., promellitic dianhydride) are made to react, for example, in an organic polar solvent (e.g. N-methyl-2-pyrrolidone) to obtain the objective polyamic acid having at least one sort of recurring unit of formula II (X is of formula III; Y is of formula IV), followed by heating said polyamic acid to effect dehydration to obtain the other objective polyimide.
