| titleOfInvention | Methoxy carboxylic acid esters and use as ultraviolet stabilizers |
| abstract | Compounds of the formula <IMAGE> are prepared and are used as ultraviolet light and weathering stabilizers for polymers, preferably polypropylene. In the formula R is alkoxyphenyl, dialkoxyphenyl or alkylene dioxyphenyl, the alkoxy groups have 1 to 8 carbon atoms and the alkylene group has 1 to 4 carbon atoms, q is 1 to 6, and Z is <IMAGE> (a) where R' is H or a 1 to 4 carbon alkyl, R7 is hydrogen or <IMAGE> where R8 is hydrocarbyl, m is 1 to 4, n is 0 or 1 and m+n is 1 to 4; <IMAGE> (b) where R12 is lower alkyl and G is H or <IMAGE> and where at least one of the n's is zero. <IMAGE> (c) where s is 1 to 3 and t is from 0 to 2, the total of s and t being not over 3; O(CH2)uO (d) where u is 2 to 4; <IMAGE> (e) where v and w are each 1 to 4 and p is 2 to 4; <IMAGE> (f) <IMAGE> (g) <IMAGE> (h) where R'' and R''' are 1 to 8 carbon atom alkyl or where R11 and R111 together with the oxygen atoms attached thereto and the adjacent carbon atoms of the benzene ring form a 5 or 6 membered heterocyclic ring and RIV is 1 to 4 carbon atom alkylene; <IMAGE> (i) <IMAGE> where x is 2 to 3; (j) alkloxy of 1 to 18 carbon atoms; (k) NHR9 where R9 is 1 to 18 carbon atom alkyl or H; <IMAGE> (l) where Y is O,R6O where R6 is 1 to 3 carbon atoms <IMAGE> or <IMAGE> and f is 2 to 4. |
