项目摘要

The photo-initiated formation of amino groups in polymer matrices and its applications to functional polymers were investigated. Copolymers bearing pendent acyloxyimino(AOI) groups used in this study were O-acryloyl acetophenone oxime(AAPO) or O-methacryloyl acetophenone oxime(HAAPO) with styrene(St) or methyl methacrylate(MMA). An yield of formation of amino groups in the photolysis of a AAPO(26.3)-St copolymer film was 69.9% and double bonds were also formed in a 28.0% yield. The yield of amino groups did not depend on comonomers, irradiation wavelengths, and irradiation atmosphere but depended on the amount of AOI groups in copolymers i.e., the yield for a homopolymer of AAPO decreased to 25%. In the case of MAAPO(28.3)-St copolymer films, the yield of amino groups under nitrogen was 21.5% but a total amount of double bonds was 62.7%, which consisted of double bonds in main-chains and vinylidene-type double bonds. Under air, the yield of amino groups did not changed but the yield of … More donds bondrdecreased to 30.2% and at the same time main-chain scissions occurred. Applications of the AAPO copolymers to functional polymers were also investigated. The treatment of irradiated AAPO copolymer films with an aqueous HC1 solution rendered the copolymer surface hydrophilic and the films dyed well with an acid dye. Before irradiation, the copolymers dissolved in non-polar solvents such as benzene and toluene but the films treated with HC1 after irradiation dissolved in polar solvents such as ethanol and methanol. On the basis of these results, the applications of AAPO copolymers to dual-tone photoresists were investigated and it was proved that these copolymers have excellent properties as a positive-type photoresist. In the case of MAAPO copolymers, although the yield of amino group formation was lower compared with that of AAPO copolymers, efficient main-chain scissions were observed and the rate of the main-chain scissions was found to be accelerated by an increase in the content of AOI groups and irradiation time. This result was explained by a lowering of glass transition temperature of irradiated copolymers. Less

研究了聚合物材料中氨基群的照片引发的形成及其在功能聚合物中的应用。本研究中使用的带有垂直甲氧基氨基（AOI）组的共聚物是O-丙烯酰乙酰苯甲酮（AAPO）或苯乙烯乙烯酮（HAAPO）和苯乙烯（ST）或甲基丙烯酸甲酯（MMA）。在AAPO（26.3）-ST共聚物膜的光解中形成氨基的产量为69.9％，双键也以28.0％的收率形成。氨基组的产量不取决于平民，照射波长和辐照气氛，而取决于共聚物中AOI基团的量，即AAPO的均聚物的产率降低到25％。在Maapo（28.3）-ST共聚膜的情况下，氮基团的产量为21.5％，但总的双键总量为62.7％，其中包括主链和乙烯基型双键的双键。在空中，氨基群的产量没有改变，但是……更多的债券债券的收益率达到30.2％，同时发生了主链科学。还研究了AAPO共聚物在功能聚合物中的应用。用水性HC1溶液对辐照的AAPO共聚物膜的处理使共聚物表面亲水性，并用酸染料染色良好。在辐照之前，共聚物溶解在非极性溶液（例如苯和甲苯）中，但是在辐照溶解在极性溶液（例如乙醇和甲基丙二醇）中后用HC1处理的膜。根据这些结果，研究了AAPO共聚物在双色调光蛋白师身上的应用，并证明这些共聚物具有出色的特性，作为阳性型光疗及其。在MAAPO的情况下，尽管与AAPO共聚物的产量相比，氨基组形成的产量较低，但观察到有效的主链科学，并且发现主链科学的速率通过AOI组含量和辐射时间的增加而加速了主链科学的速度。该结果通过降低辐照共聚物的玻璃过渡温度来解释。较少的
