Abstract

863,176. Cross-linked polyoxymethylenes. DU PONT DE NEMOURS & CO., E. I. Oct. 3, 1958 [Oct. 7, 1957(2)], No. 31640/58. Class 2(6). Cross-linked polyoxymethylenes are obtained by exposing a mixture of a polyoxymethylene containing at least 100 oxymethylene units per molecule and an ester, amide or imide containing at least 2 non-adjacent ethylenic groups, the ethylenic groups being in a terminal position or in conjunction with the oxygen atom in the C=O group of the amide, imide or ester radical, to either (a) an ionizing radiation or (b) ultraviolet light in the presence of a photoinitiator. The ester, amide or imide may have the formula R(XY)n where R is a hydrocarbon or oxygeninterrupted hydrocarbon radical, X is:- Y is an ethylenically unsaturated hydrocarbon group, and n is at least 2. The ionizing radiation may be particle radiation, such as electrons, protons, neutrons, alpha-particles, deuterons or #-particles, or ionizing electromagnetic radiation, such as X-rays or radiation from a nuclear reactor or radioactive material. When ultraviolet light is used the photoinitiator may be a vicinal dicarbonyl compound, an aromatic diketone, an acyloin ether or an α-hydrocarbonsubstituted aromatic acyloin. In examples polyoxymethylene is cross-linked with N, N<SP>1</SP>-methylenediacrylamide, m-phenylene-dimaleimide, triethylene glycol dimethacrylate, dialkyl maleate, 2, 4-tolylenedimaleimide, trialkyl cyanurate and N, N-dialkylacrylamide, by irradiation with electrons or X-rays, or with ultra-violet light using as photoinitiators benzoin methyl ether and anthraquinone. Specifications 748,336 and 753,299 are referred to.
