Abstract
Preparation of di- and triblock copolymers of styrene-h8, styrene-d8, and 2- vinylpyridine by anionic polymerization was carried out for the purpose of obtaining block copolymer samples containing a poly(styrene-d8) part and having well defined molecular characteristics. The block copolymerization proceeded successfully when the polymerization was carried out in the order of styrene-h8, styrene-d8, and 2-vinylpyridine or of styrene-d8, styrene-h8, and 2-vinylpyridine, whereas it was not successful when the polymerization was started from 2-vinylpyridine. All block copolymer samples polymerized in the order of styrene and 2-vinylpyridine were found to have narrow molecular weight distributions with respect to each component.
