摘要: 通过假高稀反应和芳香亲核取代反应成功合成制备了一种新型芳基三硫醇,并将其与烯丙基聚醚砜(c-PAES)混合得到的混合体系在光引发剂TPO的作用下能极大的增强聚醚砜体系的紫外交联速度. 研究结果表明,按官能团的摩尔比1:1的比例添加芳基三硫醇的聚醚砜体系在紫外交联情况下,其最终双键转化率提高了一倍左右,而且体系的光反应速率有了极大的提高. 交联后的聚合物的Tg升高了约20度,TGA数据表明聚合物的仍有较好的热稳定性,可作为耐高温材料使用.

Abstract: A novel trithiol, 1,3,5-tris[4-(4-mercaptophenyl sulfonyl) phenoxy] benzene (TMPSPB) was prepared via a two-step reaction. Based on this monomer, a photo-cross-linkable polyethersulfone blends system was obtained. The blends can go photo-cross-linking reaction in the presence of photo initiator. The glass transition temperatures of the copolymers increased greatly after the curing. The cured copolymers became completely insoluble in common organic solvent and exhibited outstanding thermal stability. Such work provides a new approach to prepare photo-crosslinkble poly(arylene ether ether)s without loss its high heat resistance.
