ITACONIC ACID GRAFTING ON LDPE BLENDED IN MOLTEN STATE

Grafting of itaconic acid on low density polyethylene in the molten st ate has been investigated. Static and dynamic mixers assembled on the Brabender plastograph have been used as a blender of reagents and as a chemical reactor. Shear rates were 50 and 100 s(-1). Dicumyl peroxide ; 2,5-dimethyl-2,5-di-(tert-butylperoxy)hexane; tylperoxy)-5,5,6-trime thylbicyclo-[2,2,1]-heptane; ne-3-peroxy)-5,5,6-trimethylbicyclo[2,2,1 ]heptane; 2,5-dimethyl-2-hydroxy-5-tert-butylperoxy-3-hexyne were used as peroxide initiators of grafting.
