Silane crosslinking of polyolefins
Polimery 2002, No 11-12, 762
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.
