Abstract
The reaction of monofunctional living poly(dimethylsiloxane), poly(DMS), with dimethylchlorosilane (2), followed by the hydrosilation of the polymer end SiH group with allyl alcohol was performed. The hydroxyl end group of poly(DMS) (4) thus obtained was subsequently converted to the tosylate ester group through treatment with tosyl chloride in the presence of 4-dimethylaminopyridine (DMAP). The tosylate ester end group of poly(DMS) (5) was found to initiate the cationic ring opening polymerization of 2-methyl-2-oxazoline (OXZ) to produce the poly(DMS)/poly(OXZ) block copolymer (7).
