    摘要: The present invention relates to thermoplastic moulding compositions of (A) 99.5 to 80% by weight, of at least one amorphous linear polyamide and (B) 0.5 to 20% by weight of at least one segmented thermoplastic elastomeric copolyester. These novel moulding compositions combine good toughness and hardness with good elongation and stiffness properties as well as good flowing properties of the molten material.

    摘要: A radiation-polymerizable mixture is described comprising (a) a compound which has at least two terminal ethylenically unsaturated groups and which can form a crosslinked polymer by means of free radical initiated chain addition polymerization, (b) a polymeric binder, (c) a radiation-activatable polymerization initiator which can be activated by radiation, and (d) a compound which is thermally crosslinkable with the polymeric binder (b), with the polymerization product of compound (a) and/or with itself and which, if its crosslinking groups are epoxy groups, has at least three epoxy groups. A photopolymerizable copying material is also disclosed having a flexible transparent temporary support and a transferable thermoplastic photopolymerizable layer comprising the foregoing radiation-polymerizable mixture. The photopolymerizable layer, after photocrosslinking, can be additionally cured by thermal crosslinking and is therefore suitable for the manufacture of solder resists and high performance printing plates.

    摘要: The present invention relates to novel agents for the flame-proofing of polymers, especially transparent polyamides. These agents, phosphinylphosphinic acids, are used in quantities of 3 to 40 weight percent calculated on the weight of the polymer. These flame-proofing agents can easily be prepared and render the polymers flame-proof to a high degree without deteriorating the mechanical and physical properties.
