Abstract:
1. A polymer mixture consisting of: at least one synthetic first polymer P(i) and between 3% to 14% by weight of at least one second polymer P(j), wherein the first 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, wherein the second 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, wherein the polymer mixture comprises a molecularly dispersed mixture containing P(i) and P(j) that forms a network by heterocrystallisation, wherein P(i), or the sequences A of P(i), comprises a polyethylene, wherein P(j) has a polydispersivity <30 and is a polyethylene wax; and wherein P(i) has a degree of branching <3×10
