| titleOfInvention | Continuous process for preparing a spinning solution of an acrylic polymer |
| abstract | 1472103 Production of acrylic spinning solutions MONTEFIBRE SpA 14 June 1974 [14 June 1973] 26551/74 Heading C3P A continuous process for preparing a spinning solution of an acrylic polymer directly from a bulk polymerization slurry which contains residual monomer comprises: (a) adding a solvent to the slurry to give a mixture having a viscosity less than 2 poises, but in an amount which will not dissolve the polymer; (b) heating the mixture from (a) to above room temperature and up to 170 C. but without dissolving the polymer; (c) evaporating at least 30 wt. per cent of the unreacted monomer or monomers in one or more adiabatic evaporation steps under vacuum; (d) optionally adding further solvent to give the desired concentration for the spinning solution; (e) heating the mixture to a temperature not exceeding 170 C. until the polymer is attacked and completely dissolved by the solvent and (f) if necessary removing any residual monomer or monomers by thin layer evaporation. The preferred solvent is dimethyl acetamide. In the example, the polymer is a copolymer of acrylonitrile and vinylacetate. |
