WATERBORNE ACRYLIC DISPERSIONS WITH HIGH BIORENEWABLE CONTENT

An aqueous copolymer dispersion is formed by emulsion polymerization of a monomer mixture comprising (a) 20 to 80 wt. % of one or more (meth)acrylic acid esters A, whose homopolymer(s) have a Tg>25° C. and at least one has a biorenewable carbon content of at least 50 wt. % of the total carbon con...

Zusammenfassung:	An aqueous copolymer dispersion is formed by emulsion polymerization of a monomer mixture comprising (a) 20 to 80 wt. % of one or more (meth)acrylic acid esters A, whose homopolymer(s) have a Tg>25° C. and at least one has a biorenewable carbon content of at least 50 wt. % of the total carbon content of the ester; (b) 19 to 79 wt. % of one or more (meth)acrylic acid esters B whose homopolymer(s) have a Tg
