Title:
PROCESSES TO CONTROL THE RESIDUAL MONOMER LEVEL OF COPOLYMERS OF TERTIARY AMINO MONOMER WITH A VINYL-FUNCTIONAL MONOMER
Document Type and Number:
WIPO Patent Application WO2002026844
Kind Code:
A3
Abstract:
The present invention relates to processes for making polymers from at least one tertiary amino-containing monomer and at least one vinyl-functional monomer, while controlling residual monomers and avoiding production of Michael addition adducts. The process employs one or more of the following steps to avoid such adducts, maintaining at least one tertiary amino-containing monomer an at least one vinyl-functional monomer separate until the polymerization reaction, maintaining the at least one tertiary amino-containing monomer and at least one vinyl-functional monomer free of water until the polymerization reaction, and employing high temperatures for the polymerization reaction. The polymers are useful in personal care products, fabric detergent, hand dishwashing detergent, oil well treating chemicals, fire-fighting foam, agricultural chemicals, flocculants, coagulants, and household cleaners.
