Abstract
The present invention relates to a process for preparing a polymer latex that includes polymerizing one or more ethylenically unsaturated aromatic monomers and one or more conjugated diene monomers in the presence of a hydroperoxide chain transfer agent and sulfur-containing chain transfer agent, wherein the sulfur-containing chain transfer agent is added after the hydroperoxide chain transfer agent. It further relates to the polymer latex thus obtained, to a composition comprising the polymer latex and to the use of the polymer latex or polymer latex composition in a carpet backing, paper coating, or fiber fabric pre-impregnation process.
