中文摘要：
设计了一个紫外光引发的气／固聚合反应体系，通过紫外光引发和三乙醇胺／二苯甲酮引发，在BOPP膜和玻璃表面分别直接获得了醋酸乙烯酯（VAc）聚合物。结果表明，在BOPP膜上的聚合物的交联度可达46％，而玻璃表面的聚合物溶解后可完全通过200目（0．071mm）的金属网，分子量分布分别为6．0和4．0左右。这两处的聚合物层的质量和分子量都随反应时间的延长而增加，温度升高不利于玻璃表面上聚合物分子量的增加而利于BOPP膜上附着的聚合物可滤过部分分子量的上升。根据BOPP膜上聚合物层有一定程度交联的现象，本文改进了反应裴置，在BOPP膜上获得了交联度大于95％的聚合物层，而同时在玻璃表面生成的聚合物较少，并仍可完全通过200目（0．071mm）的金属网。
英文摘要：
A new apparatus for carrying out vapor/solid polymerization initiated by UV light has been designed. The system relies on monomer photolysis and the benzophenone/triethanolamine system to initiate polymerization of vinyl acetate to afford poly （vinyl acetate） on the surface of biaxially oriented polypropylene （BOPP） film and glass respectively. The poly （vinyl acetate） formed on the surface of the BOPP film was shown to be partly crosslinked （up to 45%）, while that formed on the surface of the glass could all pass through a 200 mesh metal filter （0.071 mm）. The values of the polydispersity index （PDI） of the polymers were 6.0 and 4.0 respectively. In the case of both BOPP and glass substrates, the mass/thickness of the polymer and its molecular weight increased with reaction time. Increasing the temperature gave an increase in the molecular weight of the polymer formed on the BOPP film but not of that on glass. Mechanisms for the formation of polymer on BOPP film and glass substrates are proposed. Furthermore, after modification of the reaction apparatus, the degree of crosslinking of the polymer formed on the BOPP film was higher than 95 % and while the mass of polymer formed on the surface of glass decreased significantly, it could still all pass through the 200 mesh （0.071 mm） metal filter.
