Abstract
A polymer blend, a process for the preparation thereof and products manufactured from the polymer blend. The polymer blend contains 95 to 50 parts by weight of a polyolefin- or polyester-based polymer matrix, 5 to 50 parts by weight of an aromatic main-chain liquid crystalline polymer and plastic additives, if any. Further, the blend contains, based on the total weight of the previous components, 0.1 to 30 percent by weight of a substance (a compatibilizer) which improves the compatibility of the polymer matrix and the liquid crystalline component. The compatibilizer includes a polymer containing reactive functional groups. Preferably, the compatibilizer includes an SEBS polymer functionalized with maleic anhydride or an olefin polymer functionalized with glycidyl methacrylate.
