【摘要】 本文研究了调节羧酸钼体系1,2-聚丁二烯微观结构的因素。发现催化体系中烯丙基卤的用量、加料次序以及聚合温度能够调节1,2-聚丁二烯的乙烯基含量。烯丙基溴不仅调节1,2-立构体含量而且对其序列分布有所影响。更多还原

【Abstract】 Factors governing the microstructure of 1, 2-polybutadienes preparedwith molybdenum catalysts have been stedied. It was found that the vinylcontent of the 1,2-polybutadienes could be regulated by addition cf allylhalide and the order of addition of the catalyst components as well as thepolymerization temperature. Allyl bromide appeared more effective for theregulation of 1,2-stereoisomer and the sequence distribution as. well.更多还原
