## Abstract Amphiphilic polystyrene‐ionene diblock copolymers with blocks of controlled molecular weights were synthesized by a new method. The preparation starts with the anionic polymerization of styrene with 3‐(dimethylamino)propyl‐lithium as initiator, yielding tertiary amino end‐functionalized
ABA-type block copolymers containing segments of poly(dimethyl siloxane) and poly(vinyl pyrrolidinone) were synthesized. Dihydroxyl-terminated poly(dimethyl siloxane) was reacted with isophorone diisocyanate and then with t-butyl hydroperoxide to obtain macroinitiators having siloxane units. The per
