摘要:
The present invention relates to compounds containing dual substitutions of an aromatic amine and hindered phenol functionality useful as stabilizers for organic materials. These compounds are of general formula (I) wherein phi is formula (II). R1 and R2 are independently selected from the group consisting of hydrogen, substituted or unsubstituted aryl, and substituted or unsubstituted alkyl of 1 to 20 carbon atoms; R3 is alkylene of 1 to 10 carbon atoms; m is 0 or 1; n is an integer of 1 to 10; q is an integer of 0 to 8; z is 1 or 2, provided that, when q is 0, z must be 1; X represents the links of a chain q links in length, said links being selected from the group consisting of carbon, nitrogen, oxygen, sulfur, silicon, and mixtures thereof; and Y is an aromatic group or phi , provided that Y can be phi only when q is 0 and m is 1.
摘要:
A method for increasing the temperature stability of copolymers of ethylene, (meth)acrylates, and a cure site monomer is disclosed, wherein the method comprises grafting an aromatic amine onto the cure site monomer. More particularly, the aromatic amine contains a single primary amine moiety that is sterically unhindered.
