摘要：

The overall composition of random and block copolymers comprising two kinds of repeat units can be determined as a function of molecular weight by a new dual (e.g., UV and RI) detector GPC technique, if one of the repeat units can be specifically "seen" by one of the detectors. The method is demonstrated by the use of random copolymers of styrene (St) and isobutylene (IB) as the UV "visible" and "invisible" components, respectively. Novel triblock copolymers comprising two polyacenaphtylene (PAc) outer-segments and a polyisobutylene (PIB) mid-segment are also analyzed.
