Gas/liquid interfacial preparation of polyamide fibrids |
| abstract |
Fibrides of synthetic heterochain polymers are produced by a non-equilibrium polycondensation of an aqueous alkaline solution of bifunctional compounds supplied into the reaction zone as a continuous stream oriented in the horizontal plane of the reaction zone to be acylated with diacylchlorides of dicarboxylic acids in the state of a superheated vapor with a carrier supplied into the reaction zone in the vertical plane, the contacting of the reagents being effected in a cross-current stream under shear stress conditions. n An apparatus employed for carrying out the process for producing fibrides of synthetic heterochain polymers includes a vertically mounted cylindrical housing comprising a reaction chamber provided with means for admitting the liquid phase of the starting products thereinto as a continuous flow oriented in the horizontal plane of the reaction chamber; a chamber for generating the gas phase of the starting products positioned under the reaction chamber, and means for removing the reaction products from the reaction chamber provided in the upper part of the latter. n The present invention is useful in the manufacture of synthetic paper for electroengineering applications, in aviation engineering, fuel filters for diesel engines, in the production of plastics, and non-woven materials in the textile and light industries. |
