Macromonomers, poly vinyl styrene terminated

Charleux, B. and Pichot, C. (1993) Styrene-terminated poly(vinyl alcohol) macromonomers. 1. Synthesis by aldol group transfer polymerization. Polymer, 34, 195. 

Employing an HIPE technique, poly(aryl ether sulfone) monoliths were obtained by the copolymerization of maleimide-terminated aryl ether sulfone macromonomer with styrene, DVB, or bis-vinyl ether in a solution in which petroleum ether (80% by volume) was dispersed [373]. The resulting product possessed an open-cell structure with porous cell walls and enlarged thermostability compared with poly(styrene-co-DVB) mono-hths. Unfortunately the utilization of the material as a possible medium for chromatographic separation has not been reported. 

Normally, a maaomonomer carries only a single oligomer chain. The combination of a terminal vinyl group with two polymeric chains has also been reported. In such an example, macromonomers consisting of a methacryloyl group as a polymerizable unit and two PS or poly(tert-butyl acrylate) (PtBA) chains were prepared in two steps as shown in Figure 3 (1) ATRP of styrene or tBA was initiated by a diinitiator, 1 -hydroxymethyl-1,1 -di [ (2-bromoisobutyryloxy)...
