Abstract
In a multi-stage emulsion polymerization process, a first monomer composition comprising from about 60 weight percent to about 95 weight percent of at least one vinyl ester, and from about 5 weight percent to about 40 weight percent ethylene is polymerized in a first stage under ethylene pressure to produce a first stage product having a Tg of less than 20° C. Then, in a second stage, a second monomer composition comprising at least 95 weight percent of a meth(acrylic)ester or a mixture of at least two different (meth)acrylic esters is polymerized in the presence of said first stage product, wherein the (meth)acrylic ester(s) is selected such that the polymer produced by said second monomer composition has a Tg of 5 to 90° C.
