Fundamental research works of polymer reaction engineering rooted from the key problems in PVC manufacture were carried out along with two main aspects concerning with polymer chemistry

technololy and engineering for more than forty years.Polymerization kinetics including rate

degree of polymerization and copolymer composition

microscopic and macroscopic particle formation mechanism

and heat transfer

agitation and mixing

and scale-up technique of reactor were studied in detail.The key problems for developing new types of PVC and related polymers

and for scale-up design of new reactors were easily solved based on the fundamental researches.
