我们在前文介绍了遥爪型端双氯基聚1,2-丁二烯的合成研究,本文以上次合成的预聚物为原料,用酸、醇或硷为试剂,对聚合物的端基碳-氯键进行水解,从而获得了两端各带两个三聚氰氯酸基的“多爪”型聚1,2-丁二烯,其平均官能度f接近理论值4。我们发现末端羟基的氢可以脱离氧而与环上的氮结合,产生下列醇-酮互变异构现象: We have previously described the synthesis of telechelic dl-terminated poly-1,2-butadiene. In this paper, the last synthesis of prepolymer as raw materials, with acid, alcohol or alkaline as the reagent, the polymer end groups Carbon-chlorine bond was hydrolyzed to obtain “poly-claw” type poly (1,2-butadiene) having two cyanuric acid groups at both ends and having an average functionality f close to the theoretical value of 4. We found that the hydrogen at the terminal hydroxyl group can dissociate from oxygen and bind to the ring nitrogen, resulting in the following alcohol-ketone tautomerism:
