摘要
本文报道末端为甲基丙烯酸酯型的聚环氧乙烷大单体和聚苯乙烯大单体的合成和表征。前者分子量可在0.33—1.0×10~4范围变化,后者分子量在0.27—1.3×10~4范围变化,其分布系数分别为1.07—1.20和1.10—1.18。
The w-methacryloyl poly (ethylene oxide) (PEO-MA ) and polystyrene ( PST-MA)macromers were synthesized and characterized. The molecular weights of PEO-MA and PST-MA varied within 0.33-1.0×10~4 and 0.27-1. 3×10~4 respectively. Their distribution coefficients were 1.07-1.20 and 1.10-1.18 successively.
