Title:
LOW VISCOSITY HIGH SOLIDS COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2010/144655
Kind Code:
A3
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.
