The composition also includes hydrolysable silane groups, which may be grafted onto the ethylene-based polyolefin, or a blend of the ethylene-based and propylene-based polyolefins, in the presence of a free radical initiator. The moisture-crosslinked articles further comprise a silanol condensation catalyst to permit the silane groups to form crosslinks in the presence of moisture. After crosslinking, the article may be heated, stretched and then cooled to render it heat shrinkable.Type: ApplicationFiled: March 6, 2009Publication date: September 9, 2010Applicant: ShawCor Ltd.Inventors: Peter Jackson, Marcus P. Heydrich

Patent number: 7781524Abstract: A releasing composition capable of improving abrasion resistance includes a releasing composition containing releasing particles in a film forming material, and the releasing particle has a first releasing resin as a core material and a second releasing resin as a coating material. The first releasing resin has a relatively higher releasing property than the second releasing resin. The first releasing resin can include a surface tension of from about 0.01 N/m to about 0.025 N/m, and the second releasing resin may have a surface tension of from about 0.026 N/m to about 0.05 N/m.Type: GrantFiled: May 2, 2007Date of Patent: August 24, 2010Assignee: Sony Chemical & Information Device CorporationInventor: Takuya Monju
