摘要： In the method for solid-phase drying or solid-phase polymerizing a polyamide of the present invention, the polyamide that is stored for 20 days or longer after the production thereof until subjected to the solid-phase drying or the solid-phase polymerization under the specific conditions is used as the starting material. By storing the polyamide under the specific conditions of the present invention, the resultant solid-phase dried or solid-phase polymerized polyamide with a low yellowness is obtained even if 20 days or more time has lapsed after the starting polyamide is produced until it is subjected to the solid-phase drying or solid-phase polymerization.

摘要： In the process of the present invention, a recovered polyamide is used as a part of the raw materials for producing polyamide. By carrying out the polycondensation under a condition such that the recovered polyamide is dissolved in the reaction system during the polycondensation, the properties of the polyamide being produced are not deteriorated as compared with those of polyamide which is produced without using the recovered polyamide. By changing the addition amount of the recovered polyamide, the crystallization speed of the resultant polyamide is controlled or increased as compared when produced without using the recovered polyamide.

摘要： The invention relates to a method for carrying out polycondensation reactions, according to which the polycondensation of a monomeric starting material is carried out with external supply of heat in a reactor combination which has at least two stages and is composed of a pre-reactor and a high-viscosity reactor, where the low-molecular-weight elimination products produced are removed by evaporation. In the pre-reactor, the reaction product is concentrated to give a high-viscosity preliminary product. The high-viscosity preliminary product is then fed to the high-viscosity reactor, in which it reacts to completion with simultaneous introduction of thermal and mechanical energy and with a residence time of from 20 s to 60 min to give a polycondensation product.

摘要： There is provided a process for the continuous polymerization of polyamides which is carried out under conditions of pressure, temperature and polymer concentration in water that will ultimately yield multiple phases (including a second liquid polymer phase or a polymer precipitate). However, a single phase operation is achieved under these conditions by appropriate management of residence time and using a well-mixed reaction environment in early stages of the polymerization.

摘要： The invention concerns a polyamide comprising macromolecular chains having a star-shaped configuration, a method for making said polyamide and compositions comprising same. More particularly, the invention concerns a method for making a polyamide comprising linear macromolecular chains and star-shaped macromolecular chains with control of the star-shaped chain concentration in the polymer. Said control is obtained by using besides the polyfunctional polymers and amino acids or lactams a polyfunctional comonomer comprising either acid functions or amine functions. The resulting polyamide has optimal mechanical and rheological properties for improving the speed and quality of mould filling and producing mouldable compositions comprising high filler factors.
