Abstract
A wood protection paint comprises a copolymer emulsion prepared by an emulsion polymerization process, in which a first monomer composition comprising from 60 weight percent to 95 weight percent of at least one vinyl ester, and from 5 weight percent to 40 weight percent ethylene is polymerized in a first stage under ethylene pressure to produce a first stage product having a Tof less than 25° C. Then, in a second stage, a second monomer composition selected such that the polymer produced by the second monomer composition has a Tof at least 95° C.
