| abstract |
A process for obtaining a polyolefin composition endowed with improved adhesion performance, especially paintability, comprising premixing a high-flow polyolefin resin with one or more grafting monomers and initiator, possibly also one or more comonomers, feeding the obtained premix and a low-flow polyolefin resin into a mixing device, and gradually heating the components to above their melting points while being subjected to mixing forces. The process may be carried out in an extruder, and polyether amine may optionally be introduced into the extruding mass downstream of the feeding point. |
