ABSTRACT
Figure 2 Schematic representation of the domain structure of styrene-butadiene-styrene block copolymer.
bisperoxides was reported by Bamford and Jenkins [7] via vinyl polymerization using 4,4'-azobiscyanopentanoic acid (ACPA) in the following reaction scheme:
HOOC-cH2CHr·t-N=Ni-cH2CH2-cOOH
t-BuOO---polystyreno--.--OOBu-t
Polystyrene bisperoxides can be prepared by the termination of polystyryl anion with bromo methyl benzoyl peroxide [9]:
Macrolntermediates for Copolymers
In this manner, growing polytetrahydrofuran cations can be terminated by using sodium salt of cumenehydroperoxide (10] .
