Abstract
The invention relates to a novel synthesis process in order to produce meltable PAN copolymers with increased thermal stability. The PAN copolymers produced using the method according to the invention surprisingly exhibit improved thermal and mechanical properties compared to PAN copolymers produced using methods known from the prior art. The invention additionally relates to corresponding PAN copolymers and to molded bodies produced therefrom or to a method for producing such molded bodies, in particular melt-spun mono- or mufti-filaments.
