A thermoplastic wrap film including polyisobutylene succinic anhydride (PIBSA) is disclosed herein.

Wrap film with polyisobutylene succinic anhydride

A multi-layer film includes a first layer including a blend of diene elastomer and not greater than about 40% by weight polyolefin. The multi-layer film also includes a second layer directly contacting and directly bonded to the first layer. The second layer includes a fluoropolymer.

Multi-layer release films

A multilayer film includes a first layer including a blend of a polyolefin and a diene elastomer, a second layer directly contacting and directly bonded to the first layer, and a third layer directly contacting and directly bonded to the first layer. The second and third layers include a fluoropolymer.

The disclosure is directed to a polymer film including a first layer and a second layer. The first layer includes a first fluoropolymer and has a melting point less than 135&#xb0; C. The second layer overlies the first layer and includes a second fluoropolymer. The second layer has a melting point greater than 135&#xb0; C.

Multi-layer polymer film

Disclosed is an intercrosslinked multilayer polymeric article having at least one thermoplastic polymer layer intercrosslinked by UV radiation at the interface with a core layer of a crosslinkable polymer. The selection of the thermoplastic polymer and the crosslinkable polymer is such that a coextruded composite product of these materials has poor interlayer adhesion prior to radiation treatment. However, the interfacial intercrosslinking provides superior bonding between the layers. The same UV radiation for intercrosslinking typically can also cure the crosslinkable polymer to give the multilayer article excellent structural integrity. Also disclosed is a method for preparing an intercrosslinked multilayer polymeric article.

Multilayer structure with intercrosslinked polymer layers

An intercrosslinked multilayer polymeric article comprises (A) at least one thermoplastic polymer layer in contact with (B) at least one crosslinkable polymer layer, wherein (A) and (B) are incompatible with each other, and wherein (A) and (B) are secured together by intercrosslinking. Also disclosed is a method for preparing an intercrosslinked polymeric article.
