标题:锆茂和光氧化还原催化环氧化物的催化还原开环
摘要:环氧化物的还原性开环是一种强大的转化,可将容易获得的环氧化物转化为各种有价值的醇,包括药物,农用化学品和功能性聚合物.尽管已经取得了重大进展,但已建立的方法仅限于二茂钛催化反应.在此,我们报告了一种前所未有的由光氧化还原催化实现的由锆茂催化的环氧化物开环.与传统的开环方法相比,本方案表现出反向区域选择性,可通过假定的不太稳定的自由基提供更多的取代醇.该反应非常温和,可以顺利切割具有多种官能团的分子中的 C-O 键,包括天然产物.

标 题:Polymers prepared by polymerizing alpha, beta-ethylenically unsaturated acids and epoxy compounds
发明人：DAS SURYYA K; PORTER JR SAMUEL; TYGER WAYNE H
权利人:PPG INDUSTRIES INC
摘要:Hydroxyl-containing polymers prepared by reaction of a polymerizable alpha, beta-ethylenically unsaturated carboxylic acid and an epoxy compound containing greater than 5 carbon atoms are disclosed. The polymer is prepared by free radical organic solution polymerization techniques. Synthesis of the polymers by this technique assures multiple hydroxyl functionality in all polymer chains thereby providing good cure response. The polymers are useful as binders in high solids coating compositions. When used with appropriate curing agents, the resultant coatings have good hardness, high gloss and distinctness of image, have good solvent and humidity resistance and are very resistant to acid etching. n Preferred reactants are: n (a) an alpha, beta ethylenically unsaturated carboxylic acid and n (b) a glycidyl ester of the formula ##STR1## where R=a tertiary aliphatic hydrocarbon group of 4 to 26 carbon atoms.
