Title:
熱可塑性多層複合物
Document Type and Number:
Japanese Patent JP4726476
Kind Code:
B2
Abstract:
A multilayer thermoplastic composite (4) with layer(s) (1) based on fluoropolymers and contiguous layer(s) (2), in which layer (2) is based on a polyamide/polyamine copolymer. Independent claims are also included for (1) a polymer conduit comprising (4), in which (1) forms the inner layer with a thickness of 0.01-0.7 mm, (2) forms a coupling layer with a thickness of 0.05-0.3 mm and there is a third, outer layer (3) with a thickness of 0.2-0.8 mm (2) a polymer conduit as above in which at least one layer (preferably an inner layer) is electrically conductive and/or there is another, electrically-conductive layer inside the first layer (1) (3) a method for the production of hollow products from (4), in which the moulding material for layer (2) is obtained by homogenising a mixture of a lactam, a polyamine (especially a polyethyleneimine [PEI]) and water at elevated temperature, polymerising the mixture by heating for several hours at above 300[deg]C under pressure and then reducing the pressure and temperature .
