Diglycidyl ethers of 2-phenyl-1,3-propanediol derivatives and oligomers thereof as curable epoxy resins

摘要

Cured epoxy resins are widespread on account of their outstanding mechanical and chemical properties. It is common to use epoxy resins based on bisphenol A diglycidyl ether or bisphenol F diglycidyl ether, but for many sectors these are problematic because of their endocrine effect. The present invention relates to 2-phenyl-1,3-propanediol diglycidyl ether derivates and to curable epoxy resin compositions based thereon, as alternatives to the bisphenol A or bisphenol F diglycidyl ethers and to the epoxy resin compositions based thereon.

1. A diglycidyl ether of a 2-phenyl-1,3-propanediol derivative of formula I: which is derived from a 2-phenyl-1,3-propanediol derivative of formula II: where: R1 is an alkyl group or an aryl group, R2 and R3 or R3 and R4 optionally form a fused aromatic ring or a fused heteroaromatic ring, where R2 to R4 are otherwise each independently a hydrogen atom, an alkyl group having 1 to 4 C atoms, a halogen atom, or a nitro group, R5 and R6 are each independently a hydrogen atom, an alkyl group having 1 to 4 C atoms, a halogen atom, or a nitro group, R7 is a hydrogen atom or a glycidyl group, and n is from 0 to 100.
