【発明の名称】生物学的に分解可能な水性分散液
Document Type and Number:
Japanese Patent JP2645637
Kind Code:
B2
Abstract:
The invention relates to biodegradable, aqueous dispersions of vinyl ester polymers having a solids content of from 20 to 70% by weight, based on the total weight of the dispersion, which have been prepared by free-radical polymerisation by the emulsion polymerisation method, where a monomer phase containing a) from 50 to 100 parts by weight of one or more vinyl esters from the group consisting of the vinyl esters of unbranched or branched alkanecarboxylic acids having 1 to 15 carbon atoms, b) from 0 to 30 parts by weight of ethylene and/or esters of (meth)acrylic acid or ethylenically unsaturated dicarboxylic acids with alcohols having 1 to 10 carbon atoms, and c) from 0 to 20 parts by weight of other mono- or polyethylenically unsaturated compounds is polymerised in the presence of from 10 to 50% by weight, based on the monomer phase, of biodegradable plasticiser and from 0.5 to 15.0% by weight, based on the monomer phase, of biodegradable emulsifier and/or biodegradable protective colloid.
