✦ Synopsis

Segmented poly(ethylene oxide) macroinitiators containing bistrialkylbenzopinacolate groups were used to initiate radical polymerization of styrene. A polystyrene-PEO block copolymer is formed by the incorporation of the PEO macroinitiator. The PEO fraction in the copolymer decreases with increasing polymerization yields. Since the molecular weight of the macroinitiator is low, the incorporated PEO fraction is necessarily small in high molecular weight copolymers.

Abstraet--Poly(ethylene oxide) radical macroinitiators with built-in benzopinacolate groups were prepared by two different methods: the first one involves a hydrosilylation reaction between ct, co-difunctional polylethylene oxide (PEO) precursors and a difunctional benzopinacolate; due to the presen
