摘要:
Composite sheet structures of polyethylene and of copolyamides of .epsilon.-caprolactam, 3-aminomethyl-3,5,5-trimethyl-cyclohexylamine and isophthalic acid.
摘要:
Copolyamides with improved properties are obtained by polycondensing aliphatic and/or aromatic dicarboxylic acids with an amine mixture of diaminodicyclohexyl methanes and optionally homologous polycyclohexyl polyamines and one or more aliphatic diamines, said copolyamide being useful for the production of shaped articles such as films, sheets and injection moldings.
摘要:
Polyamide moulding materials which have been reinforced with unsized glass fibres and to which a flame-proof finish has been imparted by means of melamine or melamine cyanurate and which have a high glow wire resistance.
摘要:
This invention relates to flame-proved polyamide moulding compositions containing a combination of from 10 to 18%, by weight melamine and from 1 to 7% by weight of a thermoplastic polyacetal, in each case based on the moulding composition.
摘要:
Thermoplastical processible polyamides are rendered hydrophobic by addition of particular aromatic amines, optionally in combination with selected phenolic compounds.
摘要:
Thermoplastic, easily flowing hydrophobic polyamides obtained by incorporation of from 2 to 15% by weight, based on polyamide, of at least one monoepoxide compound corresponding to the following general formula ##STR1## in which R is a hydrocarbon radical containing at least 4 carbon atoms.
摘要:
Thermoplastic polyamides containing phenolic compounds in quantities of from 0.5 to 15%, by weight, based on polyamide are less sensitive to water.
