Title:
保護コロイド安定化された重合体、その製法及びその使用
Document Type and Number:
Japanese Patent JP4567316
Kind Code:
B2
Abstract:
Protective colloid stabilized polymers are based on homo- or mixed polymers of vinyl esters, methacrylic acid esters and acrylic acid esters, vinyl aromatic compounds, olefins, dienes and vinyl halides and contain, as protective colloid, a partially saponified vinyl acetate-ethylene copolymer comprising 1-15 mol.% ethylene, a degree of saponification for the vinyl acetate units of 80-95 mol.% and a viscosity of 2-30 mPas Protective colloid stabilized polymers (I) are in the form of aqueous dispersions or powder that is redispersible in water and are based on homo- or mixed polymers of vinyl esters of optionally branched 1-15C alkyl carboxylic acids, methacrylic acid esters and acrylic acid esters of 1-15C alcohols, vinyl aromatic compounds, olefins, dienes and vinyl halides and contain, as protective colloid, a partially saponified vinyl acetate-ethylene copolymer comprising 1-15 mol.% ethylene, a degree of saponification for the vinyl acetate units of 80-95 mol. % and a viscosity of 2-30 mPas (4 % aqueous solution, DIN 53015). An Independent claim is included for a process for the production of the polymer (I) by emulsion or suspension polymerization with optional drying of the resulting aqueous dispersion.
