    Abstract: AND 5 TO 50 MOL% OF STRUCTURAL UNITS CONTAINING HYDANTOIN RINGS AND HAVING THE GENERAL FORMULA

    The invention relates to copolyamides which have an extremely low water absorption capacity of 1 to 3.5 % but remarkably high tensile strengths of between 7 and 20 g/dtex and moduli of elasticity of between 500 and 11.000 kg.wt/mm2. The copolyamides comprise of from 50 to 95 mol.% of structural units of the general formula

    Abstract: THIS INVENTION RELATES TO ACRYLONITRILE GRAFT POLYMERS HAVING AN IMPROVED AFFINITY TO ACID DYES. THE USED GRAFT SUBSTRATES CONSIST OF LINEAR POLYAMIDES CONTAINING AT LEAST ONE QUATERNIZED NITROGEN ATOM FOR EVERY TWO AMIDE GROUPS. THE GRAFT COPOLYMERS BEING PREPARED BY POLYMERIZING ACRYLONITRILE TOGETHER WITH OTHER COPOLYMERIZABLE MONOMERS IN AN AQUEOUS MEDIUM, SAID POLYMERIZING BEING AFFECTED IN THE PRESENCE OF THE LINEAR POLYAMIDE AS GRAFT SUBSTRATE AND IN THE PRESENCE OF A REDOX-CATALYST SYSTEM.

    Abstract: THE INVENTION RELATES TO AN ACRYLONITRILE GRAFT POLYMER HAVING IMPROVED AFFINITY FOR ACID DYES COMPRISING ACRYLONITRILE BEING GRAFT-POLYMERISED TOGETHER WITH OTHER ACRYLIC OR VINYL MONOMERS AND A LINEAR POLYETHER HAVING QUATERNISED NITROGEN ATOMS AS GRAFT BASE. THE GRAFT BASE HAS A MOLECULAR WEIGHT OF ABOUT 1,000 TO ABOUT 15,000 AND THE ACRYLONITRILE GRAFT POLYMER HAS A K-VALUE (ACCORDING TO FIKENTSHCER, CELLULOSE CHEMIE 13, (1932), PAGE 58) OF FROM 70 TO 100. IN THE PROCESS OF PREPARING SAID ACRYLONITRILE GRAFT POLYMER ACRYLONITRILE AND OTHER COPOLYMERISABLE COMONOMERS ARE GRAFT-POLYMERISED IN THE PRESENCE OF A GRAFT BASE CONSISTING OF A LINEAR POLYETHER HAVING QUATERNISED NITROGEN ATOMS.
