NNEW POLYAMIDES AND OBJECTS OBTAINED FROM THEM

摘要

New polyamides comprising, on a mass basis: a) 45 to 75 % of unit x,T, x being between 4 and 12; and b) 55 to 25 % of aliphatic unit -HN-(CH2)n-CO, n being between 6 and 14, and the terpolyamides obtained by including a monomer unit c) such as the unit 6 or 6,I as replacement for part of the aliphatic unit b). The polyamide compositions thus obtained have a Tg lower than 130 DEG C, a Tm higher than 230 DEG C and good crystallisability. IMAGE
