| titleOfInvention | Process for the production of synthetic elastic polyurethanes |
| abstract | Elastic polyurethanes are prepared by reacting a polyalkylene ether glycol, polyacetal, or polythioether with an organic polyisocyanate, and if desired, a chain extender with reactive hydrogen atoms, at least one of the components containing either a quaternizable tertiary nitrogen atom, or a quaternizing aliphatically bonded halogen atom or RSO2O-group (in which R represents an alkyl or aryl radical), the resulting reaction product then being further reacted with a polyfunctional alkylation agent containing at least one of the above mentioned quaternizing groups should a tertiary nitrogen atom have been present in one of the original components, or with a compound containing at least two tertiary amino groups should one of the above mentioned quaternizing groups have been present in one of the original components. The polyether, polyacetal or polythioether may be predominantly linear and may have a M.W. of 400-10,000. Polyethers containing tertiary amino groups may be obtained by the oxyalkylation of dialkanolamines, e.g. propoxylation of diethanolamine or oxyalkylated aniline, koluidine or hydrazine. Polythioethers may be condensation products of thiodiglycol with other glycols which may also contain tertiary amino groups. Polyisocyanates containing tertiary amino groups may be prepared by reacting 2 moles of a conventional diisocyanates with, e.g. methyl diethanolamine. The chain extender may be the addition product of 2 mols of ethylene oxide or propylene oxide to monoalkylamines. The alkylation agent may be: p-xylylene dichloride; 1,3-dimethyl-4,6-di(chloromethyl)-benzene, tetrabromopentaerythritol and dibromobutane, kosylates, benzene sulphonate and naphthalene sulphonic esters. In typical Examples (1) to the reaction product of polytetrahydrofuran and 4,41 - diphenyl-methanediisocyanate were added methyldiethanolamine and then 1,3-dimethyl-4,6-bis chloromethyl benzene (9) 4,41-diphenyl methane diisocyanate and triethylene glycol - bis - m-chloromethylphenylurethane were added to polypropoxylated N-methyldiethanolamine. |
