The invention relates to novel permanently antistatic polyamide compositions comprising an aliphatic polyamide and from 0.5 to 40 % by weight, based on the polyamide composition, of a polyalkylene oxide obtained by the copolymerisation of mono-epoxides with di- or tri-epoxides.
摘要:
Sandwich laminates capable of withstanding high stresses, especially skis, can be manufactured by covering the wall of a mold cavity with a wet laminate, laying extremely fine glass fiber paper thereon and after closure of the mold introducing into the mold cavity a reaction mixture forming a rigid foamed plastic, which cures to a rigid foam core.
