文摘

Multiblock NB-COE copolymers were synthesized by cross-metathesis. SSA thermal fractionation by DSC was carried out. Degree of crystallinity, Tm, and mean crystallite size decrease with the conversion. Distribution of crystallite size differs from that in PCOE and PCOE/PNB blend. Annealing above Tm gives rise to a high-temperature endotherm.
