in situ polymerlegeringar och mikrokompositer samt foerfaranden foer framstaellning av system

摘要

The invention relates to polymer mixtures and to a process for their preparation. In this process, component B is reacted in the melt of a component A, which comprises one or more thermoplastic polymers. Component B comprises one or more compounds having the structure IMAGE The reaction of component B in component A gives linear, branched or crosslinked, high- or low-molecular weight polymers. In the structure of B, X = NH2, OH or an N-substituted lactam which has been activated by an electron-withdrawing substituent Y, of the type IMAGE where Y = CO, SO2 or R5P = O, R1, R2 and R4 are divalent or polyvalent aliphatic, aromatic, heterocyclic or heteroatom-containing segments, where R2 and R4 are preferably divalent, aliphatic or aromatic radicals (CH2)o where 1015, R3 and R5 are aliphatic, cycloaliphatic or aromatic radicals, and n and m are integers where 1m,n5, preferably m,n=1.
