Abstract: The invention relates to thermoplastic polymer mixture containing m polymers Pn, wherein m is a natural number from 1 to m and where each of the polymers has one or more functional groups with structure -(R1)x-C(O)-(R2)y- found as recurring unit of polymer Pn, wherein x and y independently are 0 or 1 and x+ y = 1; R1 and R2, independently, are oxygen or nitrogen, bound to the main polymer chain, wherein the differential curve of distribution W(M) of the polymer mixture there are at least two maximums at relative occurrence W, and after ageing of the polymer mixture at the melting point, at least two maximums at relative occurrence W. The position of the maximums ageing of the polymer mixture at its melting point is within the triple recurrent standard deviation sigma (r) of Mp in percentages from the value, related to the position of the maximums before ageing of the polymer mixture at its melting point.

Abstract: The thermoplastic mixture contains m polymers Pn, m representing a natural number higher than 1, and n is a natural number bigger than 1, and n is a natural number from 1 to m, and each of the polymers has: a) one or more functional groups with structure -(R1)x-C(O)-(R2)y- found as a recurring unit in the polymer chain of Pn, wherein x and y represent 0 or 1 and x + y = 1, R1 and R2 independent ly represent oxygen or nitrogen linked in the main polymer chain; b) numerical value - mean molecular weight Mn(Pn); c) average molecular weight Mw(Pn); d) z average molecular weight Mz(Pn); e) a heterogeneity index Mw(Pn)/Mn(Pn); and f) molecular weight Mp(Pn) and polymers Pn differ for each other by 1, 2, 3, 4, 5 and 6 of the properties of a), b), c), d), e) and f), and wherein the polymer mixturehas numerical value - mean molecular weight Mn(P)1, weight average molecular weight Mw(P)1, z - a weight average molecular weight Mz(P)1, heterogeneity index Mw(P)1/Mn(P)1 and molecular weight Mp(P)1, and after ageing of the polymer mixture at its melting point, it has numerical value - average molecular weight Mn(P)2, weight average molecular weight Mw(P)2, z - mean molecular weight Mz(P)2, heterogeneity index Mw(P)2, and molecular weight Mp(P)2 and these values Mn(P)2, Mw(P)2/Mn(P), Mz(P)2, Mw(P)2/Mn(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)1.
