Proprietary compatibilizers-cwm-impact modifiers offer a more economic solution and are widely used. These materials are formulated for specific types of polymer mixtures, viz. Blendex — polybutadiene-type compatibilizer for styren-ics, PVC, TPU, PET, EXL — an acrylic-based additive for PEST, Fusabond — maleated-PO compatibilizer for PO/PET blends, Vector — is SBS-type block copolymers with stabilizers, designed for PO/PS commingled mixtures, etc. 

The MW would seem to be important in determining the effectiveness of the interadion with the matrix polymer. There has been hide usefid data published, but Felix and Gatenholm [44] have shown that property improvements in a cellulose-filled polypropylene increase up to a limit of about 10 000 MW. As will be seen in the next sedion, a similar MW limit has been found for maleated polybutadienes (MPBD) in caldum carbonate-filled elastomers. 

Maleated polybutadienes have a number of uses, with filler modification being only a minor aspect Synthomer Corporation is one of the main general producers (maleated lithenes), although Evonik markets grades spedally aimed at the use with caldum carbonate fillers (Polyvest). 

Maleated polybutadienes have also been prepared but tended to have high gel contents.
