IPC: C08G69/28
Abstract: The present invention relates to a process for the preparation of an aliphatic or partially aromatic polyamide, in which an aqueous composition of the monomers is subjected to an oligomerization at elevated temperature and increased pressure, the reaction mixture is optionally subjected to a first decompression to reduce the water content, the (optionally decompressed) reaction mixture is heated within a short time to a temperature above the melting temperature of the polyamides and the heated reaction mixture is subjected to a (further) decompression to reduce the water content and to an after-polymerization.

Abstract: The present invention relates to a process for preparing an aliphatic or semiaromatic polyamide, in which a polyamide prepolymer is subjected to a solid state polymerization. In one example, the present disclosure provides a process for preparing an aliphatic or semiaromatic polyamide, in which a) a prepolymer of the aliphatic or semiaromatic polyamide is provided, b) the prepolymer provided in step a) is subjected to a solid state polymerization in a closed vessel at a temperature within a range from 200 to 290 C and a pressure within a range from 1.5 to 20 bar in the presence of a gas which is inert under the treatment conditions.
