Abstract
A composition suitable for molding is provided having the following components: I. from 97 to 80 parts by weight of a polyetheramide, having units based on one or more linear aliphatic diamines having from 6 to 14 carbon atoms, one or more linear aliphatic or aromatic dicarboxylic acids having from 6 to 14 carbon atoms, and one or more polyetherdiamines having at least 3 carbon atoms per ether oxygen and having primary amino groups at the chain ends, II. from 3 to 20 parts by weight of a rubber containing one or more functional groups; and where the total of the parts by weight of I and II is 100; and moldings produced therefrom.
Claims26
A composition comprising the following components:
- I. from 97 to 80 parts by weight of a polyetheramide, comprising units based on one or more linear aliphatic diamines having from 6 to 14 carbon atoms, one or more linear aliphatic or aromatic dicarboxylic acids having from 6 to 14 carbon atoms, and one or more polyetherdiamines having at least 3 carbon atoms per ether oxygen and having primary amino groups at the chain ends, wherein said polyetheramide is obtained by reacting components of a composition comprising one or more of said linear aliphatic diamines, one or more of said linear aliphatic or aromatic dicarboxylic acids, and one or more of said polyetherdiamines,
- II. from 3 to 20 parts by weight of a rubber selected from the group consisting of ethylene-α-olefin copolymers containing anhydride groups, styrene-ethylene/butylene block copolymers containing anhydride groups, ethylene-glycidyl (meth)acrylate copolymers, ethylene-(meth)acrylate-glycidyl (meth)acrylate terpolymers, ethylene-(meth) acrylate-α,β-unsaturated carboxylic anhydride terpolymers, and combinations thereof;
- and
- wherein the total of the parts by weight of I and II is 100.
