A method for producing polymers with narrow molecular weight distribution which involves combining (1) an initiator component of the formula
in which R₁, R₂ and R₃ are alkyl, aryl, or aralkyl groups, and can be the same or different, and X is an acetate, an etherate, a hydroxyl group, or a halogen, and i is a positive whole number, (2) a Lewis acid of the formula MXn in which M is titanium, aluminum, boron, or tin, X is a halogen, and n is a positive whole number less than 7, (3) an electron donor component having an electron donor number of from at least about 25 to no more than about 50, (4) a solvent for the preceding and (5) a cationically polymerizable hydrocarbon monomer component.
一种生产分子量分布窄的聚合物的方法,包括将 (1) 式中的引发剂组分
其中 R₁、R₂ 和 R₃ 为烷基、芳基或芳烷基,可以相同或不同,X 为乙酸酯、醚酯、羟基或卤素,i 为正整数;(2) 式 MXn 的路易斯酸,其中 M 为钛、铝、硼或锡、(3) 电子供体组份,其电子供体数至少为约 25 至不超过约 50;(4) 前述物质的溶剂;(5) 可阳离子聚合的烃单体组份。
