| titleOfInvention | Process for the polymerization and copolymerization of compounds containing epoxy groups |
| abstract | Homopolymers of alkylene oxides and copolymers of alkylene oxides with olefinically unsaturated monoepoxides are prepared by polymerizing the monomers in the presence of a solvent and, as catalyst, an aluminium compound of formula Al.H.X.Y.Z, where X and Y are hydrogen, halogen or secondary aliphatic or aromatic amine residues, and Z is an ether or tertiary amine, and can be dispensed with when X and/or Y is a secondary amine residue. An elastomer may be prepared from propylene oxide allyl glycidyl ether copolymers, of the type obtained by the above process, by sulphur-curing copolymers containing 1.5 to 6% of allyl glycidyl ether units and which elastomer has a high structural regularity, as evidenced by X-ray crystallography, is capable of being crystallized under traction and has a tensile strength of at least 200 kgs./cm.2. The catalyst for the polymerization process may be used in conjunction with chelating agents and/or water. The solvent is benzene, toluene or an aliphatic or cycloaliphatic hydrocarbon. Specified catalysts are aluminium trihydride, or monochloro- or dichloroaluminium hydrides, all of which have been formed into complexes with ethers or amines, monochloromonoamino - aluminium hydride, dimethylamino - aluminium hydride, and piperidino aluminium dihydride. Suitable chelating agents are acetylacetone, diacetone mono-oxime, dimethylglyoxime, acetonylacetone. Specified monomers are ethylene oxide, propylene oxide, butylene oxide, butadiene monoxide, vinyl glycidyl ether, allyl glycidyl ether, glycidyl acrylates, glycidyl methacrylates, and epichlorohydrin. |
