In this paper, the linear low density polyethylene (LLDPE) was melted and cross-linked by dicumyl peroxide (DCP) used to prepare cross-linked polyethylene (XPE). The gel content was determined by extraction method. The effect of content of cross-linker, cross- linked time, cross-linked temperature and other factors on the gel content were studied. It was found that the extraction time should be 18h for XPE. The gel content increased with the increasing of cross-linked time. When the cross-linked time was 10-15min, DCP was almost complete decomposition. The gel content was basically stable when the cross-linked temperature was 170-175 oC. The maximum of gel fraction was about 90%.

Microencapsulation Method

A common graft copolymerization method usually results in a low degree of grafting due to its poor inter-component interactions. A monomer microencapsulation method should be useful to enhance the current graft copolymerization technique. The maleic anhydride (MAH) grafted with linear low-density polyethylene (LLDPE) was successfully synthesized by monomer microencapsulation without using a direct method in order to find a high degree of grafting. The results showed that the degree of grafting of the LLDPE synthesized by microencapsulation (5.9%) was higher than that achieved with the direct method (5.0%).
