Abstract

A polyamide is produced by subjecting a lactam to activated anionic polymerization in a mould in the presence of an epoxide. Suitable epoxides are e.g. butylene-1:2-oxide, butadiene monoxide, cyclooctene oxide and phenyldeca-triene-1:4:8-monoxide, and they may contain neutral-reacting groups, e.g. -CN, -CO.O-, phenoxy, ether, thio-ether and amino groups and dibutylamino- or butylthio-groups. Particularly suitable are compounds having 2-6 epoxy groups, e.g. <FORM:1116068/C3/1> wherein R is a C2- 14 hydrocarbon group, <FORM:1116068/C3/2> wherein R is a hydrocarbon group and R1 is an aliphati C1- 6 hydrocarbon group, <FORM:1116068/C3/3> wherein R is a hydrocarbon group and <FORM:1116068/C3/4> wherein R is a hydrocarbon group. They are used in amounts of 0.05-30 wt. per cent of the lactam. Polyepoxide precondensates still containing epoxy groups are also suitable. Suitable lactams are caprolactam, enantholactam, capryllactam, capric lactam, laurolactam and C-substituted derivatives of these, e.g. 3-methylcaprolactam and 4-isopropylcaprolactam. Suitable anionic catalysts are alkali and alkaline earth metals, hydrides and hydroxides of these, sodium or potassium alcoholates, and Grignard compounds, and also alkali or alkaline earth metal derivatives of lactams. Amounts of 0.01-5% of the weight of lactam may be used of these. Suitable activators are organic acid halides, anhydrides, esters, and nitriles and also isocyanates and carbodiimides and urea derivatives, e.g. pyrrolidone-N-(carboxylic acid)-hexamethylene diamide-1:6 and triphenylmethane-4:41:411 - triscarbamidocaprolactam, and N-substituted carbamic esters and bisisoalkyl-urethanes. These may amount to 0.05-10 wt. per cent of the lactam. Conventional additives may be present, and expanding agents, e.g. cyclohexane, gasoline or gas-forming compounds, if it is desired to prepare a foam. In the example e -caprolactam is polymerized in the presence of Na-e -caprolactam, pentaery-thritol triglycidyl ether, CaSO4. 1/2 H2O and a petroleum ether/gasoline mixture. The mould is preferably heated to 80-200 DEG C. before addition of the lactam melt.
