Title:
METHOD FOR THE PREPARATION OF LOW ODOUR COPOLYMER LATEXES
Document Type and Number:
WIPO Patent Application WO/2011/079011
Kind Code:
A3
Abstract:
A method of preparing a low odour polymer latex composition comprises polymerising a monovinylidene monomer such as styrene and a conjugated diene such as butadiene in the presence of a linear alkyl thiol chain transfer agent. The resulting polymer latex is treated with an oxidising agent to oxidise residual chain transfer agent to volatile decomposition products that are then removed by steam stripping.
