摘要 |
A compatible blend of an engineering thermoplastic such as a polyamide and an olefin .polymer material is prepared by (1) making an oxidized olefin polymer material containing carboxylic acid groups or derivatives thereof, (2) extruding a mixture of (a) the oxidized olefin polymer material from step (1), (b) an engineering thermoplastic, (c) optionally, an inorganic base, and (d) optionally, a non-oxidized olefin polymer material, and (3) recovering a blend of the engineering thermoplastic, the oxidized olefin polymer material or an ionomer thereof, which acts as a compatibilizer, and, optionally, the non-oxidized olefin polymer material. The oxidized olefin polymer material can be made by treating the olefin polymer material with an organic peroxide initiator while adding a controlled amount of oxygen. |
