| titleOfInvention | Improvements in or relating to polyamides |
| abstract | A modified polyamide is made by reacting a polyamide of the general formula <FORM:0912167/IV(a)/1> (where R is an alkylene group containing from 5 to 10 carbon atoms and n is an integer of from 10 to 1,000) with an aminoalcohol of the general formula <FORM:0912167/IV(a)/2> (where R2 is hydrogen or an alkyl or hydroxyalkyl group) in a molar ratio of the polyamide to the aminoalcohol of from about 200 to 1 to about 10:1 and at a temperature above 170 DEG C. but below a temperature causing any substantial decomposition of the reaction product or the reactants. Specified polyamides are polycaprolactam, polycapryllactam and polyundecyllacatam. Specified aminoalcohols are tris-(hydroxymethyl)aminomethane, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol and 2-amino-1,3-propanediol. In the examples:-(I) polycapryllactam is reacted with tris(hydroxymethyl)aminomethane; (II) polyundecyllactam is reacted with tris(hydroxymethyl)aminomethane; (III) polycaprolactam is reacted with tris(hydroxymethyl)aminomethane. |
