Title:
流動化特性を有するポリビニルアルコールで安定化された再分散粉末、その製造方法および使用
Document Type and Number:
Japanese Patent JP4727940
Kind Code:
B2
Abstract:
Redispersion powder with liquefying properties manufactured by drying polyvinyl alcohol-stabilised polymer dispersions in presence of copolymers of: (a) unsaturated mono- or di-carboxylic acids; (b) unsaturated comonomers with sulfonic, sulfuric or phosphonic acid groups; and (c) vinyl esters and/or alkyl (meth)acrylates. Polyvinyl alcohol (PVAL)-stabilised redispersion powder (I) with liquefying properties, manufactured by drying PVAL-stabilised aqueous dispersions of homo- or co-polymers of vinyl 1-18C carboxylates, 1-15C alkyl (meth)acrylates, dienes, olefins, vinylaromatics and/or vinyl halides in presence of a copolymer (II) of: (a) monomer(s) selected from 4-8C unsaturated monocarboxylic acids, 4-8C unsaturated dicarboxylic acids or anhydrides, or their salts; (b) unsaturated compounds with sulfonic, sulfuric or phosphonic acid groups and their salts; and (c) comonomer(s) selected from vinyl 1-18C carboxylates and 1-15C alkyl (meth)acrylates. An independent claim is also included for a method as described above for the production of (I).
