| titleOfInvention | Oligomeric hindered amine light stabilizers based on multi-functional carbonyl compounds and methods of making same |
| abstract | Oligomeric compounds and methods of making the compound having the formula:wherein i, j, k, and l are integers from about 0 to 300 and the sum of i, j, k, and l is greater than 2, wherein the units F, F' and T are derived from one or more multi-functional carbonyl compounds of general structurewherein n is an integer from 1 to 15, m is either 0 or 1; Ra, Rb, Rc, and Rd, are each a hydrogen or a hydrocarbyl group; Y is CO-(CReRf)p, wherein Re and Rf are each a hydrogen or hydrocarbyl group and p is zero or an integer from 1 to 20 or CO-C6H4-, wherein the substitution pattern on the phenylene group is an ortho, meta, or para substitution pattern, and one or more of the hydrogens of the phenylene group may be substituted by a hydrocarbyl group or a functional group; and D is a hydrocarbyl group and the units E, E' and S are derived from one or more 1-substituted piperidin-4-ol or 4-aminopiperidines of general structurewherein Z is OH or NHG, wherein G is H or C1-C12 alkyl, R1 is -(CH2)s-OH or -(CH2)s-NH2, wherein s is an integer from 1 to 10; R2 represents hydrogen, C1-C8 alkyl, or benzyl; R3, R4, R5, and R6 are each a hydrogen, C1-C8 alkyl, benzyl or phenethyl, or two geminal R moieties, which together with the carbon to which they are attached form a C5-C10 cycloalkyl. The compounds are useful for stabilizing polymer compositions against photo- and thermal degradation. |
