Addition of Reactive Low-Molecular-Weight Compounds

An alternative compatibilization strategy is to add one or more low-molecular-weight compounds which can react with both blend components. Typical examples of these are peroxides and/or bifunctional compounds. Although the 

In order to form block copolymers in blends of polycondensates, it is possible to use bisepoxides that react with the end groups of the blend components. A combination of peroxide and unsaturated bifunctional components (MA, triallylisocya-nurate, low-molecular-weight unsaturated rubber) was reported to induce copolymer formation in PS/PE and polyolefins blends [157-159].
