| titleOfInvention | Melamine-based light stabilizers for plastics |
| abstract | Melamine-based compounds having a multiplicity of 2,2,6,6-tetraalkyl piperidine moieties are useful as light stabilizers for organic polymers. The compounds have the formula: (see fig. I) wherein: R is the group: (see fig. II) R1 is selected from hydrogen and an alkyl group having 1-5 carbon atoms, R2 is selected from the group consisting of hydrogen, oxyl, hydroxyl, a straight or branched chain methylene-linked alkyl group having 1-18 carbon atoms, an alkanoyl group having 2-18 carbon atoms, an alkenyl group having 3-4 carbon atoms, an alkenoyl group having 3-6 carbon atoms, an alkynyl group having 3-6 carbon atoms, a cyanomethyl group, a 2,3-epoxypropyl group, a benzyl or alkylbenzyl group having 7-15 carbon atoms, a group having the formula -CH2CH(OR3)-R4, and a group having the formula -(CH2)m-C(O)-Z wherein Z is selected from OR5 and -N(R6)(R7) when m is 1 or 0 and when m is 0, Z can be the group -C(O)-OR8, R3 is selected from the group consisting of hydrogen, an aliphatic group having 1-18 carbon atoms, an araliphatic group having 7-15 and an alkanoyl group having from 2-18 carbon atoms, R4 is selected from the group consisting of hydrogen, an alkyl group having 1-16 carbon atoms and phenyl, R5 is selected from the group consisting of an alkyl group having 1-18 carbon atoms, a cycloalkyl group having 5-12 carbon atoms, allyl, benzyl, phenyl and a group of R, R6 and R7, may be the same or different, and each is selected from the group consisting of hydrogen, an alkyl group having 1-8 carbon atoms, a cycloalkyl group having 5-12 carbon atoms, an alkaryl group having 6-10 carbon atoms, an aralkyl group having 7-15 carbon atoms, and additionally R6 and R7, together with the N-atom to which they are attached, can form a 5-7 membered ring consisting of pyrrolidine, piperidine and homopiperidine, R8 is selected from the group consisting of an alkyl group having 1-18 carbon atoms, phenyl and benzyl, and B is a divalent alkylene group having 1-10 carbon atoms, and Y is selected from -O- and -NH-. |
