Patent number: 9150685Abstract: 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.Type: GrantFiled: November 7, 2013Date of Patent: October 6, 2015Assignee: BASF SEInventors: Ulrich Karl, Monika Charrak, Hans-Josef Thomas, Nicolas Marion
