(57) [Summary] A latex is thickened with a compound of the following formula. R 1 - (O-A) a -B 1 -R 2 - (B 2 -R 3) d - (B 3 - (A'-O) bf - (A'-B 4) f -R 4 - ( B 5 -R 5) e) n -B 6 - (A "O) c -R 6 of formula, R 1 and R 6 is an aliphatic group, substituted aliphatic group, aromatic group and substituted aromatic group A monovalent hydrophobic group independently selected from the group, wherein R 2 and R 4 are independently selected from the group consisting of an aliphatic group, a substituted aliphatic group, an aromatic group and a substituted aromatic group; Is divalent or trivalent, R 3 and R 5 are independently selected from hydrogen, lower alkyl and lower aralkyl, and B 1 , B 2 , B 3 , B 4 , B 5 and B 6 are oxygen atoms (ethers). forms a bond -O-), carboxymethyl form a methoxide group (ester bond R 2 -C (O) -O- and / or R 4 -C (O) -O-) , amino group (amine bond R 2 -N R) - and / or R 4 -N (R) - (wherein, R is hydrogen, lower alkyl, to form a lower aralkyl, or lower acyl) and amide groups (amide linkage R 2 -N (R) -C ( O)-and / or R 4 -N (R) -C (O)-, wherein R forms hydrogen, lower alkyl, lower aralkyl or lower acyl), a bond independently selected from the group consisting of A, b, c, d, e, f, and n are each an integer, a and c are each independently any integer greater than 20 and up to about 200, and b is greater than 20 and about 450. Are any integers up to, d, e and f are 0 or 1, n is any integer from 1 to about 5, A, A ′ and A ″ are each independently ethylene, 1,2- Propylene, 1,2-butylene units or combinations thereof It |
