Abstract
A composition comprising a formaldehyde polymer and an organic polymer containing t.-amine groups may be made by bringing anhydrous monomeric formaldehyde into contact with an inert organic liquid medium, in the presence of a t.-amino-nitrogen-containing polymer and maintaining the medium at a temperature of from - 120 DEG C. up to the boilingpoint of the medium until polymerization occurs. Organic polymers mentioned are copolymers of lauryl methacrylate and betadiethylaminoethyl methacrylate, copolymers of lauryl methacrylate, methacrylanilide, and 4-dimethyl-aminocyclohexyl methacrylate, copolymers of 2-ethyl hexyl acrylate, betadiethylaminoethyl methacrylate and propylene, homo- and co-polymers of p- (beta-diethyl-amino) - styrene, 2 - vinyl - 5 - ethyl pyridine, diallylamine, beta-diethylaminoethyl acrylate or methacrylate, beta - di - n - butylaminoethyl acrylate or alpha-ethyl acrylate, beta-dicyclohexyl-aminoethyl acrylate or methacrylate, 4 - (beta - methacrylyloxyethyl) morpholine, 1(beta - methacrylyloxyethyl) - piperidine, N - (beta - dimethylamino - ethyl) acrylamide, the products obtained by reductively aminating ethylene/carbon monoxide polymers as described in Specification 652,566, and condensation polymers such as polyamides obtained by reacting dodecyliminodiacetic acid with pentamethylenediamine, e.g. polymers described in Specification 543,426. The t.-amino-nitrogencontaining polymers function as both initiators and dispersing agents, and supplementary initiators may be present such as methyl, ethyl, butyl, octyl, dodecyl, octadecyl, dibutyl, ethyloctyl, octadecyldimethyl, tributyl, trihexyl, cyclohexyl, or diphenylamine, or triphenylphosphine, tritolylphosphine, trixylylphosphine, trinaphthylarsine, tributylphosphine, triethylstibine, or methyldioctylarsine. The inert organic medium may be cyclohexane, methylcyclohexane, 1,4-dimethylcyclohexane, butane, isobutane, propane, benzene, toluene, xylene, kerosene, or mixtures. The compositions may be made into films, filaments, bristles and fibres. Specification 475,131 and 475,132 also are referred to.
