    Abstract: A thermoplastic polymer mixture comprising m polymers Pn, where m is a natural number greater than 1 and n is a natural number from 1 to m, where n is a natural number from 1 to m, where each of the polymers has one or more functional groups of the structure -(R )x-C(O)-(R )y- present as repeat units in the main chain of polymer Pn where x and y, independently of one another, are 0 or 1, and x+y=1 R and R , independently of one another, are oxygen or nitrogen bonded into the main polymer chain, where in the differential distribution curve W(M) determined to DIN 55672-2 in hexafluoroisopropanol as eluent the polymer mixture has at least two maxima of the relative frequency W, and after aging of the polymer mixture at the melting point of the polymer mixture determined to ISO 11357-1 and 11357-3 for 5 minutes, the polymer mixture has in the differential distribution curve W(M) determined to DIN 55672-2 in hexafluoroisopropanol as eluent at least 2 maxima of the relative frequency W, and the position of the maxima here after aging of the polymer mixture at the melting point of the polymer mixture is within three times the recurrent standard deviation sigma(r) of MP in percentage of the value measured to DIN 55672-2, based on the position of the maxima prior to aging of the polymer mixture at the melting point of the polymer mixture.

    Abstract: The invention relates to a thermoplastic polymer mixture containing m, m representing a natural number higher than 1, polymers Pn wherein n represents a natural number between 1 and m, and at least one recurring functional group contained in the Pn polymer chain, said group(s) having the structure -(R )x-C(O)-(R )y- wherein x and y independently represent 0 or 1, and x+y=1, and R , R independently represent oxygen or nitrogen linked into the main polymer chain. The polymers Pn differ in terms of at least one characteristic related to molecular weight. The polymer mixture has a number average molecular weight Mn(P)1, a weight average molecular weight Mw(P)1, a Z average molecular weight Mz(P)1, a heterogeneity index Mw(P)1/Mn(P)1, and a molecular weight Mp(P)1 defined according to DIN 55672-2 in hexafluoroisopropanol as an elution agent. After maintaining the polymer mixture at the melting point of the same, defined according to ISO 11357-1 and 11357-3, for five minutes, the polymer mixture has a number average molecular weight Mn(P)2, a weight average molecular weight Mw(P)2, a Z average molecular weight Mz(P)2, a heterogeneity index Mw(P)2/Mn(P)2, and a molecular weight Mp(P)2 defined according to DIN 55672-2 in hexafluoroisopropanol as an elution agent. The values Mn(P)2, Mw(P)2, Mz(P)2, Mw(P)2/Mn(P)2 and Mp(P)2 lie within the triple replication standard deviation sigma (r) in relation to Mn(P)1, Mw(P)1, Mz(P)1, Mw(P)1/Mn(P)1 and Mp(P
