Abstract

The classical free radical binary polymerization formula was processed by data processing software (maple)

and three sets of graphs of copolymerization relationship between binary monomers were calculated and plotted. The first graph is the free radical copolymerization curve

1(monomer unit concentration-monomer concentration)of the binary monomer

the second graph is the relationship between the average monomer composition (

p) and the

and the third graph is the relationship between polymer conversion rate (C) and

1. Through two groups of representative copolymerization examples

non-ideal copolymer (styrene-acrylonitrile copolymer) with constant ratio point and non-ideal non-constant ratio copolymer (styrene-vinyl acetate copolymer) respectively

the mapping steps were showed and the polymer conversion process under different race polymerization rate was analyzed.
