On the reactivity of aromatic acrylates in free-radical copolymerization with SO2 and terpolymerization with SO2 and 1-heptene

Add time:07/23/2019    Source:sciencedirect.com

The free-radical copolymerization of SO2 with phenyl, p-t-butylphenyl, p-nitrophenyl and 1-naphthyl acrylates and the terpolymerization of those monomers with 1-heptene were studied. The maximum content of sulphonyl monomeric units in copolymers varies from 13 to 24% depending on the induction and steric effects of the acrylic substituents. The composition of terpolymers varies over a very wide range depending on the reactant mole ratio and conversion. The composition of both copolymers and terpolymers is only affected to a small extent by temperature, contrary to the analogous reactions with alkyl acrylates.
