Abstract

Epoxy resins which have been prepared by reacting a phenol with at least two moles of a conjugated diene in the presence of an alkane sulphonic acid, tin tetrachloride or boron trifluoride or a complex thereof as catalyst and then epoxidizing the resulting alkenyl ether of the alkenyl phenol to give a polyepoxide containing at least one epoxyalkyl and at least one epoxyalkoxy group bound to an aromatic nucleus, are cured with phthalic anhydride. Examples describe the curing of epoxidized butenyl phenol butenyl ethers. Specifications 828,364 and 841,589 are referred to.ALSO:A process for the manufacture of alkenyl or cyclo-alkenyl ethers of alkenyl or cyclo-alkenyl phenols comprises reacting 1 mol of a phenol with at least 2 mols of a conjugated diene in the presence of an alkane sulphonic acid, in tetrachloride or boron trifluoride or a complex thereof as catalyst. The reaction preferably takes place at 0 DEG C.-30 DEG C. using 3-8 mols of diene and boron trifluoride diethyl etherate as catalyst. Lists of suitable phenols and dienes are given. Examples describe the reaction of butadiene with phenol, m-cresol, resorcinol, b -naphthol and bis-(p-hydroxyphenyl)-dimethylmethane and of isoprene and dicyclopentadiene with phenol. A mixture of products are obtained; using phenol and butadiene, for example, butenyloxy butenylbenzene, bis (butenyloxy - phenyl)-butane and (butenyloxyphenyl)-(butenyl-oxy-butenylphenyl) butane are obtained. Epoxides containing at least one epoxyalkyl and at least one epoxyalkoxy group bound to an aromatic nucleus are obtained by epoxidising the unsaturated phenol ethers, for example, with an organic per acid. Specifications 828,364 and 841,589 are referred to.
