Rate matched copolymerization

This invention relates to a method for controlling copolymer architecture by a two-part process. In the first step, a monomer analysis is obtained from a test polymerization having constant rate co-monomer addition. In the second step a copolymer is polymerized using a co-monomer feed rate that has...

Zusammenfassung:	This invention relates to a method for controlling copolymer architecture by a two-part process. In the first step, a monomer analysis is obtained from a test polymerization having constant rate co-monomer addition. In the second step a copolymer is polymerized using a co-monomer feed rate that has been adjusted based on the monomer analysis to produce a copolymer with highly controlled polymer architecture. The method can predict feeds rates to produce any desired polymer architecture from a purely random polymer to a tapered polymer. The method works for terpolymers as well as copolymers.
