Abstract
A copolymer is made by feeding one or more added olefinic monomers into a reaction vessel containing a non-homopolymerizable olefinic monomer heated to a temperature of at least about 100° C. The process may be performed in a batch or continuous fashion, may use an unpressurized reactor, may be performed without added solvent, and may form a copolymer whose number average molecular weight is less than about 4,000 amu and whose polydispersity is less than about 3.
Claims29
A process for making a copolymer, which process comprises:
- a) providing a reaction vessel containing a non-homopolymerizable olefinic monomer heated to a temperature of at least 100° C.;
- and
- b) feeding one or more added olefinic monomers into the non-homopolymerizable olefinic monomer in the presence of a free radical initiator to form a copolymer of the added olefinic and non-homopolymerizable olefinic monomers.
