Abstract:
1. A composition comprising one or more emulsion copolymer which has a broad measured glass transition temperature (measured Tg) and which are the copolymerization product residue of from 20 to 80 wt. %, based on the total weight of monomers used to make the copolymer, of vinyl monomer composition A containing one or more vinyl monomer A, and from 20 to 80 wt. %, based on the total weight of monomers used to make the copolymer, of vinyl monomer composition B having a Hansch parameter of at least 3.2, and containing one or more vinyl monomer M, such that each of which vinyl monomer(s) M would when homopolymerized provide a homopolymer having a measured Tg of 20° C. or less, wherein the total amount of vinyl monomer(s) M in vinyl monomer composition B is from 30 to 100 wt. % of the total amount vinyl monomer(s) M used in vinyl monomer compositions A and B, and, further wherein, the vinyl monomer compositions A and B are selected such that a single-stage copolymer made from the total vinyl monomer composition used to make the emulsion copolymer would have a measured Tg of from 0 to 70° C.
