High reactivity thermosettable molding compositions containing 2-methyl-1,3-propanediol.

摘要

Styrene-soluble unsaturated polyesters useful in high reactivity molding resin compositions wherein the diol component comprises from about 10 to 100 mole percent 2-methyl-1,3-propanediol. Molded thermoset articles can be obtained from these compositions using short cycle times and have unexpectedly high flexibility, tensile strength and modulus.
