BIO-RENEWABLE SEQUENTIAL VINYL POLYMER

摘要

An aqueous polymer dispersion comprising a vinyl polymer with at least two phases comprising: A) 40 to 90 wt% of a vinyl polymer A having a glass transition temperature in the range of from -50 to 30 °C; and B) 10 to 60 wt% of a vinyl polymer B having a glass transition temperature the range of from 50 to 130 °C; wherein vinyl polymer A comprises 0.1 to 10 wt% of at least one acid-functional olefinically unsaturated monomer, wherein at least 20 wt% of the monomer composition used to form vinyl polymer A and vinyl polymer B is derived from at least one bio-renewable olefinically unsaturated monomer.
