封端剂苯甲酸、丙烯酸、α-甲基丙烯酸对产物收率、粘度、溶解性、颜色等的影响不大，产物收率在90%以上，比浓对数粘度在0.035～0.060dL/g之间。
As the capping agent , benzoic acid , crylic acid and α - methacrylic acid do not largely affect the yield , viscocity , solubility and colourity . The yied was more than 90 % and the viscidity was in the range of 0.035 ~ 0.060 dL / g.
