摘要:合成了一系列1,3,5-三嗪,并测试了它们的紫外线吸收性能.利用计算化学方法构建了定量的结构-性质关系(qspr),并将其用于新型1,3,5-三嗪紫外线吸收剂化合物的计算机辅助设计.实验性紫外线吸收数据与使用时变密度泛函理论(td-Dft)[b3Lyp / 6-311 + G(d,P)]的预测数据非常吻合.合适的预测模型(r > 0.8,P <0.0001).利用sybyl程序的多重拟合分子比对规则,建立了可预测的三维定量结构-性质关系(3D-Qspr)模型,该结论与td-Dft计算吻合.对这种紫外线吸收剂化合物的异常光稳定性机理进行了研究,并证实其主要归因于它们通过超快激发态质子转移(esipt)进行激发态失活的能力.1,3,5-三嗪化合物的分子内氢键(imhb)是激发态质子转移的基础,已通过红外光谱,紫外光谱,不同构象异构体的结构和能量方面以及前沿分子轨道分析进行了探索.

摘要:Provided is a semi-aromatic polyamide, comprising, on the basis of the molar content of all repeating units, the following repeating units: 46‑54 mol% of 10T unit derived from 1,10‑diaminodecane and terephthalic acid, 46-54 mol% derived from one or more monomers in diacid Y containing 4-36 carbon atoms, and XY unit consisting of one or more monomers in diamine X containing 4-36 carbon atoms; the 10T unit and XY unit in the semi-aromatic polyamide chain segment are arranged in an alternating order ... 10TXY10TXY10TXY 10TXY10TXY ...; the semi-aromatic polyamide at least contains three monomers. In the semi-aromatic polyamide prepared by means of the special preparation method, 10T and XY units are arranged alternately, and in comparison with ordinary random copolymerized semi-aromatic polyamides, it has higher crystallinity and a higher melting point, and the water absorption rate is low.

标题:Addition of non-reactive UV absorbers during polyester synthesis
发明人：SAKELLARIDES STEFANOS L; SHARPS JR GORDON VINCENT
权利人:TORAY PLASTICS AMERICA INC
摘要:A method of incorporating a UV light absorber into a polyester during the esterification or the condensation process by selecting the UV absorber from a class that is substantially not reactive with the polyester raw materials, is stable in the conditions of polycondensation or polymerization, and does not suffer loss through volatilization, resulting in an incorporation yield of 70% or higher, preferably 90% or higher. One embodiment comprises selecting the appropriate compound from the class of triazines and incorporating is as a solid powder in the beginning of the esterification. Another embodiment comprises selecting the appropriate compound from the class of triazines and incorporating it in the form of slurry during the time interval between esterification and condensation. Other embodiments include novel resins and films made by the UV absorber containing polyester resin made by the methods disclosed herein.
