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:
Ester-modified polyamides containing of from 50 to 80% by weight of --HN--(CH.sub.2).sub.5 --CO units are obtained by reaction of .gamma.-caprolactam and mixtures of dicarboxylic acids, primary diamines and polyalkylene glycols and are suitable inter alia as hot melt adhesives and for the elastification of thermoplastic materials.
摘要:
Polymer blends with improved impact strength consisting essentially of a polyamide and a copolymer of an .alpha.-olefine, an amide and an ester of an .alpha.,.beta.unsaturated carboxylic 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:
A moulding composition consisting of:From 60 to 93 parts, by weight, of a polyamide;From 6 to 30 parts, by weight, of a polyethylene; andFrom 1 to 20 parts, by weight, of a copolymer of an aromatic vinyl compound, an .alpha., .beta.-unsaturated mono- and/or di-carboxylic acid or an anhydride thereof, free acid groups optionally being neutralized by a mono- and/or poly-amine or with ammonia, and an ester of the said mono- and or di-carboxylic acid.
