    摘要: A naphthalene derivative of the following general formula (1) having at least one allyl or propenyl group is described. ##STR1## In the formula, each G represents a hydrogen atoms or ##STR2## R.sup.1 's independently represent a hydrogen atom, an allyl group or a propenyl group provided that at least one or R.sup.1 's is an allyl group or a propenyl group, and R.sup.2 's independently represent a hydrogen atom, an unsubstituted or substituted monovalent hydrocarbon group having from 1 to 6 carbon atoms, or a halogen atom. The derivative is useful for modifying curable resins or resin compositions to provide cured products which have a low water absorption, high strength and a high glass transition temperature. The derivative has good working properties and a good heat resistance.

    摘要: Polyethers having improved barrier to oxygen are normally solid, thermoplastic polyethers having aromatic ether repeating units in their backbones and pendent hydroxyl moieties and pendent amido, N-substituted amido and/or hydroxyalkyl moieties. Such polyethers are prepared by reacting diglycidyl ethers of dihydric aromatic compounds such as the diglycidyl ether of bisphenol A with dihydric phenols having pendent amido, N-substituted amido and/or hydroxyalkyl moieties such as 2,2-bis(4-hydroxyphenyl)acetamide and 3,5-dihydroxybenzamide.
