E. Merz et al., INTRAMOLECULAR REACTIONS IN VINYL-POLYMERS AS A MEANS OF INVESTIGATION OF THE PROPAGATION STEP, Journal of polymer science. Part A, Polymer chemistry, 34(1), 1996, pp. 5-12
The Flory-Wall expressions for the fraction of substituents remaining
on a vinyl copolymer, when substituents are removed at random from adj
acent 1,3 positions, are extended to the case of nonrandom copolymeriz
ation. A copolymer composition equation is derived for the case in whi
ch the type of monomer preceding the active free-radical chain end aff
ects the propagation reaction. The distribution of lengths of sequence
s in copolymers is discussed.
