  • Patent number: 6388026
    Abstract: A process for preparing low molecular weight homomacromers and comacromers which includes (a) charging a reactor with (i) ethylenically unsaturated monomers selected from the group consisting of acrylic monomers or monoalkenyl aromatic monomers and (ii) if said ethylenically unsaturated monomer is not a thermally initiating monomer, a free radical polymerizable initiator, to form a polymerizable reaction charge. The reaction charge is heated during continuous mixing in the reactor to reaction temperature in the range from about 180° C. to about 500° C. for a residence time greater than 5 minutes to form the low molecular weight homomacromers or comacromers. If the residence time is 60 minutes or less, the reaction temperature is greater than 270° C. and if the reaction charge is a mixture of acrylic monomer and monoalkenyl monomer and the residence time is 60 minutes or less then the reaction temperature is greater than 310° C.
