Rh. Jin et al., CONTROLLED POLYMERIZATION OF AN AB(2) MONOMER USING A CHLOROMETHYLARENE AS COMONOMER - BRANCHED POLYMERS FROM ACTIVATED METHYLENE-COMPOUNDS, Macromolecular rapid communications, 19(1), 1998, pp. 41-46
Hyperbranched and branched polymers were synthesized by one-pot reacti
on of the AB(2) monomer 4-(4'-chloromethylbenzyloxy)phenylacetonitrile
(1). The polymerization of 1 was controlled by adding a chloromethyla
rene (A(1) comonomer) such as methoxybenzyl chloride and by adding TBA
C (tetrabutylammonium chloride). Copolymerization of 1 with A(2) comon
omers, bis(chloromethyl)arenes, gives the corresponding copolymers.
