含磺酸异丁酯单元的热敏树脂及其成像性能研究

On Thermo-sensitive Polymer Containing Isobutyl Sulfonote Unit and Its Imaging Properties

为了构筑高亲和性变化成像体系,合成了p乙烯基苯磺酸异丁酯单体(IBSS),并将其与苯乙烯(St),甲基丙烯酸(MAA)共聚得到一种热敏树脂,通过IR1、H NMR、GPC、DSC、TG分别确认了其结构、组成、分子量、热分解和热稳定性,并采用该树脂与红外染料匹配构筑热敏成像体系。结果表明,该树脂在100℃以下具有较好的热稳定性,由该树脂构筑的热敏成像体系经过曝光、显影后能够发生较大的亲和性变化,得到较清晰的图像。

To design high affinity switchable imaging system, a monomer isobutyl p - styrenesulfonate （IBSS） and its copolymer with styrene （St） and methacrylic acid （MAA） were synthesized. The structure, composition, molecule weight, thermolysis property and thermal stability of the synthesized copolymer were confirmed by IR,^1H NMR,GPC,DSC and TG.. Also the synthesized copolymer was applied as thermo-sensitive imaging system with an IR dye absorbing effectively at 830nm. The results showed that the copolymer was thermally stable at 100℃, and the thermo-sensitive imaging system containing the copolymer become completely soluble in neutral water after exposure, and an image was obtained.
