我们合成的端异丙黄原酰基液体氯丁二烯预聚物(XLCR),存在着室温下易结晶、流动性逐渐降低的缺点。本实验采用加入少量苯乙烯(St)与氯丁二烯(Cp)共聚的方法,可使预聚物(XLCR-B)的抗结晶性得到较大提高。
The isoprenoid-based liquid chloroprene prepolymer (XLCR) we synthesized has the disadvantage of easy crystallization at room temperature and the decrease of fluidity. In this experiment, adding a small amount of styrene (St) and chloroprene (Cp) copolymerization method, the prepolymer (XLCR-B) can be greatly improved crystallinity.
