Title:
IMPROVEMENT ON COPOLYMERIZATION OF UNSATURATED ESTER
Document Type and Number:
Japanese Patent JPS6084309
Kind Code:
A
Abstract:
The reaction cycle time for the copolymerisation of unsaturated esters such as alkyl fumarates and vinyl acetate, and for the polymerisation of methacrylates and acrylates may be dramatically reduced by carrying out the polymerisation at elevated temperatures and pressures. An additional feature is the addition of initiator during polymerisation which leads to improved products especially for lubricating oil pour depressants and fuel and crude oil flow improvers.
