PCT No. PCT/CH95/00207 Sec. 371 Date May 28, 1996 Sec. 102(e) Date May 28, 1996 PCT Filed Sep. 19, 1995 PCT Pub. No. WO96/10597 PCT Pub. Date Apr. 11, 1996A copolyamide with an improved modulus of elasticity for the melt-spinning of filaments consists of at least 75 wt. % of a linear polyamide base polymer with a melting point of 150 DEG -320 DEG C. and at least 0.5 wt. % of a block comonomer which is incorporated into the base polymer and has a glass transition temperature (Tg) between 130 DEG and 330 DEG C. and a degree of polymerization (DP) of <100. The filaments produced from the modified copolymer with an initial modulus of 500 to 1500 cN/tex are suitable for use in the production of technical fabrics.
