Color stabilized unsaturated interpolymers
Abstract
Abstract THIS INVENTION RELATES TO THE STABILIZATION AND ESPECIALLY THE COLOR STABILIZATION OF CERTAIN UNSATURATED HYDROCARBON POLYMERS WHICH ARE NON-RUBBERY INTERPOLYMERS OF A CYCLIC POLYENE AND A LEAST ONE MONOOLEFIN, SAID INTERPOLYMER HAVING AN ESSENTIALLY SATURATED CARBON CHAIN CONTAINING A SUBSTANTIAL PROPORTION OF THE TOTAL CARBON ATOMS IN THE POLYMER MOLECULE AND CONTAINING SUFFICIENT ETHYLENICALLY UNSATURATED GROUPS IN THE POLYMER MOLECULE TO PERMIT SUBSTANTIAL CURING OF FILMS THEREOF BY AN OXIDATIVE MECHANISM, SAID INTERPOLYMERS HAVING AN INTRINSIC VISCOSITY OF 0.6 OR LESS. THE STABILIZERS, WHICH DO NOT PREVENT OXIDATIVE CURE, ARE A COMBINATION OF EPOXIDES SUCH AS EPOXIDIZED SOYBEAN OIL OR EPOXIDIZED HIGHER FATTY ACID ESTERS AND TRI(ALKYLPHENYL)PHOSPHITES.
