在不同的苯乙烯配比下,进行了α-蒎烯共聚合的研究。结果表明,在共聚反应中,α-蒎烯单体的聚合速率、转化率以及聚合产物的分子量和软化点随苯乙烯用量的增加而增加。苯乙烯既是共聚单体,又是抑制α-蒎烯正碳离子的脱H~+反应的共催化剂。
Under the different ratio of styrene, α-pinene copolymerization was studied. The results showed that the polymerization rate, the conversion of α-pinene monomer and the molecular weight and softening point of the product increased with the increase of styrene content in the copolymerization. Styrene is both a comonomer and a cocatalyst that inhibits the de-H ~ + reaction of α-pinene-positive carbon ions.
