  • Copolymerisation of unsaturated esters
    Patent number: 5179182
    Abstract: The reaction cycle time for the copolymerization of unsaturated esters such as alkyl fumarates and vinyl acetate, and for the polymerization of methacrylates and acrylates may be dramatically reduced by carrying out the polymerization at elevated temperatures and pressures. An additional feature is the addition of initiator during polymerization which leads to improved products especially for lubricating oil pour depressants and fuel and crude oil flow improvers.
