Title: Polyolefin compsns for extrusion as cable jackets - prepd by reacting powdered olefin (co)polymer with a silane
Inventor: PIEPER DETLEF DIPL CHEM
IPC: B29C48/05
Filed: 1974-04-18
Abstract: Olefin (co)polymers are processed, esp. for prodn. of cable jackets or insulation, by (a) thoroughly mixing the powdered or granular polymer with a silane and a cpd. (I) which produces free radical positions in the polymer, in liq. form or in soln., and reacting the polymer with the silane, (b) shaping the reacted polymer by extrusion, with addn. of a silanol condensation catalyst before or during the conversion, esp. shaping the polymer into a cable jacket, and (c) cross-linking by action of moisture or water. Use of powdered or granular polymer avoids mechanical working and simplifies the process. Smooth surfaces and homogeneous compsn. are obtd. even with thin-walled prodts.
