Abstract

1,273,986. Optical brightening of macromolecular materials. PROCTOR & GAMBLE Ltd. 27 Aug., 1969 [23 Aug., 1968], No. 41041/ 68. Heading D1P. [Also in Divisions C2 and C5] Macromolecular and polymeric organic materials, such as nylon and wool, are brightened by incorporating or applying thereto a polythienyl compound of the general formula: wherein X represents R, OR, OM or NRR', (R and R' each represent an alkyl, substituted alkyl radical or H atom and M is a cation) Y is H, halogen, alkyl or substituted alkyl and n is 2 or 3. In the Example pieces of Nylon 6 and Nylon 66 material were washed with a detergent composition containing Na dodecyl benzene sulphonate, Na toluene sulphonate, Na tripolyphosphate, Na silicate, coconut ethanolamide, Na carboxymethyl cellulose, Na sulphate and Na perlaurate together with the optical brightener 5-propionyl-2, 2'-bithienyl, 5-acetyl-2, 2'-bithienyl, 5-methyl-5'-formyl-2, 2'- bithienyl, or 5-ethyl-5'-acetyl-2, 2'-bithienyl.
