Abstract

1,238,868. Modified polyamides. SNIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 26 July, 1968 [8 Aug., 1967], No. 35790/68. Heading C3R. The affinity of nylon 6 and nylon 66 to dyes is improved by adding 0À05 to 2 mole per cent of organic nitrogen compound to the monomer or to the polymerization mixture during polymerization but before the relative viscosity exceeds 2À3. The organic nitrogen compound must contain at least 7 carbon atoms and be either (a) a compound of formula RNHR<SP>1</SP>, where R is branched alkyl, alicyclic or aromatic and R<SP>1</SP> is H, CH 3 , a C 2-8 acyl group, a C 2-11 carboxyalkyl group, a C 2-11 aminoalkyl group optionally substituted on the nitrogen atom with a C 2-8 acyl group or an amino-aliphatic-aromatic group optionally substituted on the nitrogen atom with a C 2-8 acyl group, provided that when R is H or CH 3 , R is a branched alkyl, cycloalkylalkyl or aralkyl group bonded to the nitrogen atom through a CH 2 group; (b) a salt or amide of such a compound; or (c) a compound of formula where R 1-3 are each alkyl, alicyclic or aryl and R 4 comprises a C 1-10 carbon chain. Compounds specified include: benzylamine, hexahydrobenzylamine, 4 - methylhexahydrobenzylamine, 2,2,2 - tripropylethylamine, N - methylbenzylamine, N - methylhexahydrobenzylamine, N- methyl - 2,2,2 - tripropylethylamine, N - isopropyl - s - aminocapronic acid, N - benzyl- # - aminocapronic acid, N - cyclohexyl - #- aminocapronic acid, N - tolyl - # - aminocapronic acid, N - benzyl - α - aminobutyric acid, N - cyclohexyl - α - aminobutyric acid, N- isobutyl - α - aminobutyric acid, N - cyclohexyl - s - aminoundecanoic acid, 1 - benzylamino - 3 - aminopropane, 1 - hexahydroxylylamino - 3 - aminopropane, 1 - cyclohexylamino - 3 - aminopropane, 1 - isopropylamino- 4 - aminobutane, 1 - benzylamino - 6 - aminohexane, N isopropyl - m - xylylene diamine, N - benzylacetamide, N - (4 - methylbenzyl)- acetamide, N - hexahydrobenzylpropionamide, 1 - phenyl - N - acetyl - 3 - aminopropane, 2- methyl - N - pentanoyl - 3 - aminopropane, phenyldimethyl betaine, phenyldipropyl betaine, triethyl betaine, N - trimethyl - α- aminobutyric acid, cyclohexyldipropyl betaine, N - triethyl - α - aminopropionic acid, N - tripropyl - # - aminocapronic acid, triethyl - #- aminoundecanoic acid, methylbenzylammonium acetate, hexahydrobenzylammonium acetate, N - benzyl - # - aminoundecanoic acid, benzylammonium acetate, 1 - benzylamino - 3- aminopropane monoacetate, 1 - (N - cyclohexyl - N - methyl) - amino - 3 - aminopropane monoacetate, 1(N - cyclohexyl - N - methyl)- amino - 3 - aminopropane; 1 - isobutylamino- 6 - aminohexane, 1 - isopropylamino - #- aminoundecane, 1(N - isobutyl - N - acetyl) and amino - 3 - N<SP>1</SP> - acetylaminopropane. In examples TiO 2 is added to the spinnable polymer.
