Abstract

This paper covers the knowledge of different procedures of polyalkene crosslinking. Besides the crosslinking, the effect of crosslink formation on the properties of polyolefins which may be of use in various applications have been dealt with.

Crosslinking methods based on the recombination of macroradicals and/or condensation of silanes are discussed, taking into account parallel side reactions which are decisive factors in the resulting crosslinking efficiency and network structure. From crosslinking pathways occurring through free radicals, radiolytic, photolytic and thermally induced generation of macroradicals and subsequent reactions of reactive intermediates are described in more detail.

Although much is already known in this field, the possibilities of its exploitation has not been fully explored yet. As an example, the idea of the recombination and disproportionation of low molecular alkyl radicals as an explanation of the crosslinking efficiency of polyolefins may be put forward. Of equal importance is to define the problems which await a more detailed study as well as to interpret sometimes controversial results and particularly to elaborate new principles of physical crosslinking of polyalkenes or chemically induced crosslinking of oriented macromolecules.

The paper uses the information from 198 references, of which one quarter were published in 1988.
