Abstract
Polymer mixtures containing a first long-chain polymer and a second short-chain polymer. The structural parameters of the two polymers are coordinated in such a way that a polymeric material is obtained which is easier to process while being provided with improved mechanical properties and in part also improved thermal properties compared with the first polymer at suitable conditions for producing the polymer mixture as a result of networks being formed and heterocrystallization taking place.

1-12. (canceled)
A polymer mixture containing at least one synthetic first polymer P(i) and at least one second polymer P(j) and optionally a swelling agent for P(i) and/or P(j), wherein the polymer P(i) has a degree of polymerisation DP(P(i))>500 and at least one type of crystallisable sequences A having a degree of polymerisation DPs(P(i)) of these sequences>20 and the polymer P(j) is made up of the same monomer units as the sequences A of P(i) and the degree of polymerisation DP(P(j)) of P(j) is 20<DP(P(j))<500 and the polymer mixture comprising a molecularly dispersed mixture containing P(i) and P(j) forms a network under heterocrystallisation.
