Editing Polyethylene (section)

===Chlorination and sulfochlorination===
[[Chlorinated Polyethylene]] (PE-C) is an inexpensive material having a chlorine content from 34 to 44%. It is used in blends with [[Polyvinyl chloride|PVC]] because the soft, rubbery chloropolyethylene is embedded in the PVC matrix, thereby increasing the [[impact resistance]]. It also increases the weather resistance. Furthermore, it is used for softening PVC foils, without risking the migrate of plasticizers. Chlorinated polyethylene can be crosslinked peroxidically to form an elastomer which is used in cable and rubber industry.<ref name="Domininghaus" /> When chlorinated polyethylene is added to other polyolefins, it reduces the flammability.<ref name="Kaiser" />{{rp|245}}

Chlorosulfonated PE (CSM) is used as starting material for ozone-resistant [[synthetic rubber]].<ref>[http://www.chemgapedia.de/vsengine/vlu/vsc/de/ch/9/mac/andere/kautschuk/kautschuk.vlu/Page/vsc/de/ch/9/mac/andere/kautschuk/chlorsulfon.vscml.html Chlorsulfoniertes Polyethylen (CSM)].
