  • New polyglycidyl ethers
    Patent number: 3937685
    Abstract: The object of the invention are new polyglycidyl ethers and a method for their production, which ethers give a new mixture of the type mentioned which can be cured like a thermosetting resin, that is to say an epoxide resin system which can be crosslinked to give thermosetting resin compositions, which possess improved heat distortion points and good mechanical properties, and especially no excessive brittleness.
