A series of tri-block copolymers of styrene/tetradecyl methyl acrylate/3-methacryloxyl-propyl thimethoxyl silane was synthesized by atom transfer radical polymerization. The structures of those copolymers were characterized by means of gel permeation chromatography, infrared spectrum, and nuclear magnetic resonance (1H-NMR). Effect of tri-block copolymers on the mechanical properties of glass fiber/polypropylene composites was also investigated.

采用原子转移自由基聚合法合成了一系列新的三嵌段共聚物大分子偶联剂聚苯乙烯－b-聚甲基丙烯酸十四酯－b-聚3-甲基丙烯酰氧基丙基三甲氧基硅烷，通过凝胶渗透色谱、红外光谱和核磁共振(1H-NMR)证实了其结构，并研究了其对玻璃纤维／聚丙烯复合材料力学性能的影响。

Aiming at the shortcomings of high formaldehyde content and low soaping and crocking fastnesses of currently used pigment printing binder,by60Co-γ radiation polymerization process,the waterborne polyacrylate emulsion containing active keto groups was synthesized from acrylate monomers and diacetone acrylamide.

针对目前所用涂料印花黏合剂存在的色牢度低和甲醛含量高的缺陷，采用钴60-γ辐射法聚合工艺，利用丙烯酸酯单体、双丙酮丙烯酰胺合成出含活性酮羰基的丙烯酸酯乳液；然后同含端酰肼基聚氨酯乳液按一定的比例混合，制备出酮肼交联型丙烯酸酯聚氨酯复合乳液。
