Abstract
Official abstract text for this publication.
The invention relates to a composition including: 45 to 95 wt % of a semi-aromatic copolyamide containing at least two separate units having the following general formulation: A/X.T, where A is selected from among a unit obtained from an amino acid, a unit obtained from a lactam, and a unit having the formula (diamine Ca).(diacid in Cb), and XT denotes a unit obtained from the polycondensation of a diamine in Cx and from terephthalic acid, with x being the number of carbon atoms of the diamine in Cx, said copolyamide having a polymoleoularity index, noted Ip, of less than or equal to 3.5, measured by gel permeation chromatography, and an amino chain end content of between 0.020 meg/g and 0.058 meg/g; and 5 to 55 wt % of at least one cross-linked polyolefin. The invention also relates to a method for preparing said composition and to the uses thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising: from 45% to 95% by weight, relative to the total weight of the composition, of a semiaromatic copolyamide comprising at least two different units corresponding to the formula: A/X.T, in which A is a unit obtained from an amino acid, a unit obtained from a lactam or a unit corresponding to the formula (Ca diamine).(Cb diacid), with a representing the number of carbon atoms in the diamine and b representing the number of ca…
