Title:
CROSS-LINKABLE POLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO2003040192
Kind Code:
A3
Abstract:
The invention pertains to a polymer obtainable from the steps: - polymerizing a mixture, that is substantially free or organic solvents, of ethylenically unsaturated monomers which consist for at least 70% of methacrylates, and which comprises specific chain transfer agents, alpha-methylstyrene dimer being preferred, to form a first polymer, - aqueous emulsion polymerizing a mixture comprising ethylenically unsaturated monomers in the presence of the first polymer to form a dispersion of a water-insoluble second polymer, wherein these steps are preferably performed in the absence or the substantial absence of a surfactant.
