Abstract
Disclosed are compositions comprising a textile treating resin and a novel copolymer of a maleic-anhydride copolymer and a fatty acid amine and an aminoorgano-polysiloxane. Said compositions are useful for increasing the water and oil repellency of substrates such as textiles, paper, leather and the like.
Claims12
A composition comprising a) from about 0.02 weight % to about 2.0 weight % of a textile treating resin which is a fluorine-containing polymer of any polymeric or polymer-forming perfluoroalkyl-group-containing compound, sufficient to impart oil or water repellency to a textile fabric and b) from about 0.15 weight % to about 10 weight % of a copolymer of (I) a maleic-anhydride copolymer of the formula ##STR52## wherein each of R.sub.1 and R.sub.1 ' is hydrogen, lower alkyl, lower alkoxy, or aryl, and n is an integer from 2 to 30, (II) an amine derived from fatty acid and of the formula CH.sub.3 -(CH.sub.2).sub.p -NH.sub.2, wherein p is an integer from 7 to 28, and (III) an aminoorganopolysiloxane of the formula ##STR53## wherein R.sub.2 is lower alkyl, R.sub.3 and R.sub.4 are each lower alkylene, and n is an integer from 5 to 28.
