本文采用溶液法以单酚(4-氯-4’-羟基二苯砜)为原料合成了不同聚合度的单酚低聚体,得到了控制聚合度的最佳聚合条件;用相转移催化剂法成功地将单酚转化为单烯大分子单体,并用IR、1H—NMR对其结构进行了表征;测定了双键官能度均在1.90以上.单烯大分子单体与苯乙烯的共聚研究表明,聚合度为2左右的单烯大单体在苯乙烯中溶解度最大,可达80%以上;共聚物有优异的光学特性,对折射率的提高比相应的双烯大分子单体有利;在可见及近红外区透光率达89%以上.
In this paper, monophenol oligomers with different degree of polymerization were synthesized by the solution method using monophenols (4-chloro-4’-hydroxydiphenylsulfone) as raw materials, and the optimum polymerization conditions for controlling the degree of polymerization were obtained. The conversion of monophenol to mono-olefin macromonomer was successfully carried out. The structure was characterized by IR and 1H-NMR. The double bond functionalities were all above 1.90. The copolymerization of mono-olefin macromonomer and styrene showed that the degree of polymerization of about 2 is the largest solubility of styrene in the monomer, up to 80%; copolymer has excellent optical properties of the refractive index Higher than the corresponding diene macromonomer favorable; in the visible and near infrared transmittance of more than 89%.
