摘要： THE PHYSICAL PROPERTIES OF GLYCIDYL ETHERS OF GLYCERINE ARE IMPROVED BY BLENDING A POLYHYDROXYL-CONTAINING COMPOUND, SUCH AS GLYCERINE, WITH SAID GLYCIDYL ETHER IN PROPORTIONS SUCH THAT THE RATIO OF EPOXIDE EQUIVALENTS TO HYDROXYL EQUIVALENT IN THE BLEND IS IN THE RANGE OF FROM ABOUT 1.8:1 TO ABOUT 0.5:1. WHEN SUCH BLENDS ARE CURED WITH CATALYTIC QUANTITIES OF A CURING AGENT, SUCH AS A TERTIARY AMINE, ONE OR MORE OF THE PHYSICAL PROPERTIES SUCH AS TENSILE STRENGTH, PERCENT ELONGATION AND TENSILE MODULUS ARE IMPROVED.

摘要： Epoxy resins which are glycidyl ethers of glycerine having improved physical properties, when cured to a thermoset condition, are the dehydrohalogenated reaction products of A. a mixture comprising from 0 to 49 percent by weight of a polyhydroxyl containing compound, such as polyglycerol, and from about 51 to 100 percent by weight of glycerine with B. a mixture comprising (1) 0.05 to 0.65 epoxy equivalents per mole of A of a polyepoxide, such as the diglycidyl ether of bisphenol A, and (2) from 1.35 to 2.95 epoxy equivalents per mole of A of an epoxy alkyl halide such as epichlorohydrin. When such products are cured with a catalytic quantity of a tertiary amine, they exhibit improved physical properties such as tensile strength, elongation, or tensile modulus.
