【摘要】 <正> 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:更多还原

【Abstract】 The thesis is primarily based on dichlorotelechelic polybutadiene-1,2 prepared first by using naphthalenelithium as initiator, extracted naphtha as solvent, butadiene as monomer, trichloroazine as terminator. Then acetic acid or alcohol or sodium hydroxide was used to hydrolyze dichloro telechelic polybutadiene-1,2 to obtain thecorresponding end product--telechelic cyanuric acid terminated polybutadiene-1,2.The latter was studied in detail by ultraviolet, infrared spectrum and acid-base potential titration. Not only the molecular structure of said prepolymer was testified but also the phenomenon of alcohol-ketone (lactam-lactim) tautomerism present in polymer solution was discovered as well. They were measured quantitatively, too.更多还原
