Reactive Compatibilization
“Reactive compatibilization of immiscible polymer blends is a method which is very often used to obtain well dispersed and stabilized phase morphologies. The technique of reactive compatibilization is based on the in-situ formation of a block- or graft copolymer at the interface between the phases of a polymer blend during melt-mixing. In some cases, a third polymer, which is miscible with one of the blend components and reactive with the other, can be used for the formation of a compatibilizing copolymer at the interface” [Dedecker and G. Groeninckx, Pure & Appl Chem, 70 #6, 1289-1293 (1998)]

In situ reactive compatibilization of polypropylene/epoxidized natural rubber blends by electron induced reactive processing: novel in-line mixing technology
(2257–2263)Polymers for Advanced Technologies 22 #12 (2011)
Rooj et al of the Indian Institute of Technology, India, prepared blends of polypropylene (PP) and epoxidized natural rubber (ENR) by an in-line electron induced reactive processing technique. The mixing was done in a Brabender mixing chamber coupled with an electron accelerator. The electron induced reactive processing of PP in presence of TAC before adding of ENR performed the best amongst all samples modified with electrons investigated in this study. (RDC 11/25/2011)
