Silane crosslinking of polyolefins

Polimery 2002, No 11-12, 762


DOI: dx.doi.org/10.14314/polimery.2002.762

Summary

A review, mainly of last 5 years, on the subject of fundamentals as well as technology of polyolefins' crosslinking with vinylalkoxysilanes (Fig. 1) on the background of other methods of such polymers' crosslinking. Three base steps of this technology have been detaily presented, as follows: preparing of the polymer being able to crosslink (either by grafting of vinylsilane onto polyolefin or by copolymerization of olefin with vinylsilane), hydrolysis of alkoxysilane groups to silanol groups and condensation of the last ones with creation of -C-Si-O-Si-C- bonds connecting individual macromolecules. Thermal and mechanical properties of the products obtained this way (mainly all of PE-HO, PE-LO, PE-LLO and PP products) as well as their practical importance have been also described.
