GRAFT POLYETHYLENE Russian patent published in 2013 - IPC C08F255/02 C08L51/06 C08L43/04 C08F8/12 

FIELD: chemistry.

SUBSTANCE: disclosed is a method of grafting hydrolysable silane groups to polyethylene, involving reaction of polyethylene at temperature higher than 140°C with a saturated silane, having at least one hydrolysable group bonded to Si, in the presence of a compound of agents capable of generating free-radical centres in polyethylene, characterised by that the silane contains an acryloxyalkyl, bis(trialkoxy-silylalkyl)fumarate and/or bis(trialkoxy-silylalkyl)maleate group. Disclosed also is use of said silane in grafting hydrolysable silane groups to polyethylene and a method of cross-linking polyethylene obtained using the disclosed method.

EFFECT: method enables to obtain silane-modified polyethylene with high grafting efficiency, which can be rapidly cross-linked and in which content of volatile organic substances can be reduced considerably.
