Gas-fade inhibitor and anti-gas-fade polymer composition

Claim 1

An anti-gas-fade polymer composition which consists essentially of a polymer selected from the group consisting of polyurethanes and cellulose acetates and not more than 10% by weight, based on the polymer, of an inhibitor which is a triazine derivative of the following formula: ##SPC11## wherein X and Y are the same or different and each represent a member selected from the group consisting of -N<, --S-- and --O--, and wherein when X is -N<, n is 1, when X is --S-- or --O--, n is zero, when Y is -N<, m is 1, and when Y is --S-- or --O--, m is zero; each of A, B and R is a member selected from the group consisting of alkyl groups having 1 to 18 carbon atoms, alkenyl groups having 3 to 18 carbon atoms, cycloalkyl groups having 3 to 6 carbon atoms, a benzyl group, chloro-substituted benzyl groups, cyanoalkyl groups having 3 to 5 carbon atoms, dialkylamino groups having 2 to 8 carbon atoms, a phenylamino group, a phenyl group, and halogen or C 1-4 alkyl substituted phenyl groups, with the proviso that A, B and R do not represent a phenyl group or substituted phenyl group at the same time, and that when each of X and Y is --S-- or --O--, R is not a phenyl group or substituted phenyl group; each of D and E is a member selected from the group consisting of a hydrogen atom and the same groups as represented by A, B and R, A and E or B and D may together form a morpholino, piperazino, or piperidino group together with X and Y, when both of E and D are groups other than a hydrogen atom, R is not a phenyl group or substituted phenyl group, when only E is a hydrogen atom, both A and R are not phenyl groups or substituted phenyl groups, and when only D is a hydrogen atom, both B and R are not phenyl groups or substituted phenyl groups; and the sum of the number of carbon atoms contained in A, B, D, E and R is at least 10.

Claim 14

A method of inhibiting gas-fade in polyurethanes and cellulose acetates, comprising incorporating not more than 10% by weight of an inhibitor at any time from the preparation of the polyurethanes or cellulose acetates to the final finishing of shaped articles made therefrom, said inhibitor consisting essentially of a triazine derivative expressed by the following formula ##SPC12## wherein X and Y are the same or different and each represent a member selected from the group consisting of -N<, --S-- and --O--, and wherein when X is -N<, n is 1, when X is --S-- or --O--, n is zero, when Y is -N<, m is 1, and when Y is --S-- or --O--, m is zero; each of A, B and R is a member selected from the group consisting of alkyl groups having 1 to 18 carbon atoms, alkenyl groups having 3 to 18 carbon atoms, cycloalkyl groups having 3 to 6 carbon atoms, a benzyl group, chloro-substituted benzyl groups, cyanoalkyl groups having 3 to 5 carbon atoms, dialkylamino groups having 2 to 8 carbon atoms, a phenylamino group, a phenyl group, and halogen or C 1-4 alkyl substituted phenyl groups, with the proviso that A, B and R do not represent a phenyl group or substituted phenyl group at the same time, and that when each of X and Y is --S-- or --O--, R is not a phenyl group or substituted phenyl group; each of D and E is a member selected from the group consisting of a hydrogen atom and the same groups as represented by A, B and R, A and E or B and D may together form a morpholino, piperazino, or piperidino group together with X and Y, when both of E and D are groups other than a hydrogen atom, R is not a phenyl group or substituted phenyl group, when only E is a hydrogen atom, both A and R are not phenyl groups or substituted phenyl groups, and when only D is a hydrogen atom, both B and R are not phenyl groups or substituted phenyl groups; and the sum of the number of carbon atoms contained in A, B, D, E and R is at least 10.

Claim 15

A method of inhibiting gas-fade in polyurethanes and cellulose acetates, comprising incorporating not more than 10% by weight of an inhibitor at any time from the preparation of the polyurethanes or cellulose acetates to the final finishing of shaped articles made therefrom, said inhibitor consisting essentially of a triazine derivative expressed by the following formula ##SPC12## wherein X and Y are the same or different and each represent a member selected from the group consisting of -N<, --S-- and --O--, and wherein when X is -N<, n is 1, when X is --S-- or --O--, n is zero, when Y is -N<, m is 1, and when Y is --S-- or --O--, m is zero; each of A, B and R is a member selected from the group consisting of alkyl groups having 1 to 18 carbon atoms, alkenyl groups having 3 to 18 carbon atoms, cycloalkyl groups having 3 to 6 carbon atoms, a benzyl group, chloro-substituted benzyl groups, cyanoalkyl groups having 3 to 5 carbon atoms, dialkylamino groups having 2 to 8 carbon atoms, a phenylamino group, a phenyl group, and halogen or C 1-4 alkyl substituted phenyl groups, with the proviso that A, B and R do not represent a phenyl group or substituted phenyl group at the same time, and that when each of X and Y is --S-- or --O--, R is not a phenyl group or substituted phenyl group; each of D and E is a member selected from the group consisting of a hydrogen atom and the same groups as represented by A, B and R, A and E or B and D may together form a morpholino, piperazino, or piperidino group together with X and Y, when both of E and D are groups other than a hydrogen atom, R is not a phenyl group or substituted phenyl group, when only E is a hydrogen atom, both A and R are not phenyl groups or substituted phenyl groups, and when only D is a hydrogen atom, both B and R are not phenyl groups or substituted phenyl groups; and the sum of the number of carbon atoms contained in A, B, D, E and R is at least 10.
