Synthetic resin stabilizers based on quadratic acid amides

Claim 1

Compositions comprising synthetic resins having about 0.01-5% by weight of stabilizers based on the total weight of said synthetic resins wherein said synthetic resins are selected from the group consisting of polymers of olefins, diolefins, vinyl acetate, ether esters, urethanes, isocyanurates, acrylonitrile, styrene, vinyl chloride, polyamides, polyether amides, polyester amides, polyether ester amides or mixtures thereof; and said stabilizers are selected from the group consisting of bisamides of quadratic acid of the general Formulas I, II, or mixtures of I and II: ##STR3## wherein R 1 , R 2 , R 3 , and R 4 represent: (A) hydrogen, alkyl groups having 1-22 carbon atoms, alkylene groups having 1-22 carbon atoms, hydroxysubstituted alkyl groups having 1-22 carbon atoms or hydroxysubstituted alkylene groups having 1-22 carbon atoms; (B) cycloalkyl groups having 6-12 carbon atoms, cycloalkyl groups having 6-12 carbon atoms and substituted with alkyl groups having 1-6 carbon atoms, cycloalkyl groups having 6-12 carbon atoms and bound to the nitrogen atoms of Formula I by alkylene groups having 1-5 carbon atoms or cycloalkyl groups having 6-12 carbon atoms and bound to the nitrogen atoms of Formula II by alkylene groups having 1-5 carbon atoms; (C) phenyl groups, phenyl groups substituted with alkyl groups having 1-4 carbon atoms, phenyl groups substituted with hydroxy groups, phenyl groups substituted with hydroxy groups and alkyl groups having 1-4 carbon atoms, phenyl groups bound to the nitrogen atoms of Formula I by alkylene groups having 1-3 carbon atoms or phenyl groups bound to the nitrogen atoms of Formula II by alkylene groups having 1-3 carbon atoms; (D) 3-6 member heterocyclic groups having 1-3 nitrogen atoms, 3-6 member heterocyclic groups having 1-3 oxygen atoms, 3-6 member heterocyclic groups having 1-3 oxygen atoms, 3-6 member heterocyclic groups having 1-3 oxygen and nitrogen atoms, said heterocyclic groups substituted with alkyl groups having 1-3 carbon atoms, said heterocyclic groups bound to the nitrogen atoms of Formula I by alkylene groups having 1-5 carbon atoms or said heterocyclic groups bound to the nitrogen atoms of Formula II by alkylene groups having 1-5 carbon atoms; (E) said ##STR4## groups defining heterocyclic groups having 3-6 members, said ##STR5## groups defining heterocyclic groups having 3-6 members where 1 or 2 of said members are nitrogen or oxygen, said heterocyclic groups substituted with 1-4 carbon alkyl groups, hydroxy groups or oxogroups; and (F) respectively R 1 and R 3 or R 2 and R 4 represent unbranched or branched, ring-anellated, saturated or unsaturated aliphatic chains.
