On February 1, 2018, Peters, Edward Norman published a patent.Application In Synthesis of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione The title of the patent was Epoxy hardener composition and associated forming method, uncured and cured epoxy resin compositions, and article. And the patent contained the following:
A hardener composition comprising: (A) 1 to 80% of a hydroxyl-diterminated poly(phenylene ether) having an intrinsic viscosity of 0.03 to 0.2 dL per g measured by Ubbelohde viscometer at 25° in chloroform; and (B) 20 to 99% of an anhydride having structure I wherein q is zero or 1, Ra is C1-C6-alkyl, and X is -CH2-, -(CH2)2-, -O-, or -S-; wherein the hardener composition exhibits a single glass transition temperature from -80 to 200°, wherein the single glass transition temperature has a value of -46 to 110°; and wherein the hardener composition comprises zero to 1% of solvents for the hydroxyl-diterminated poly(phenylene ether). Also disclosed are a method of forming the hardener composition, a curable epoxy composition incorporating the hardener composition, a cured composition formed from the curable epoxy composition, and an article that includes the cured composition The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Application In Synthesis of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione
