The present application is directed to a film they may be used as an adhesive for solar panels. For example, the present application is directed to a composition, for example an adhesive composition, comprising a low crystalline poly-alpha-olefin resin having and an alkoxysilane functional poly-alpha-olefin having a tensile strength of less than 500 MPa. The composition has a melt flow index of less than 30. The application is also directed to a panel comprising a front panel comprising a transparent barrier, a back panel and a photovoltaic material layer between the front panel and the back panel. An adhesive layer is between the front panel and the back panel, wherein the adhesive layer adheres the front panel to the back panel, and the adhesive layer comprises a low crystalline poly-alpha-olefin elastomer blended with an alkoxysilane functional polyolefin.

A process that involves the in-line polymerization of olefinic monomer(s) and catalyst systems comprising a transition metal species that mediates the polymerization of the monomer(s) is disclosed. This process provides the immediate use of the resultant polymer without extensive further processing.

Compositions radiation-curable to pressure sensitive adhesives comprise (1) one or more copolymers of .alpha.-olefins of which 90.1 to 99 mole percent are one or more straight chain .alpha.-olefins, having 2 to 10 carbon atoms of which at least 55% have 6 to 10 carbon atoms, and 9.9 to 0.1 mole percent are one or more .alpha.-olefins having 6 to 20 carbon atoms and at least one methylidyne group; (2) an effective amount of a photoactive hydrogen abstracting agent; and, optionally, (3) a tackifying resin. The compositions, on exposure to radiation, provide adhesive films useful in adhesive applications, especially where a bonded article is to be used at elevated temperatures.

A piece of microwave-active tape which is odor-free and physiologically inert can be adhered to a food package and remains strongly adhered during cooking at temperatures of at least 200.degree. C. The tape has layers of microwave-active material and a pressure-sensitive adhesive which is a polymeric .alpha.-olefin that has been cured to afford a 'Peel Value' of at least 5 N/dm and a 'Shrink Back' at 220.degree. C. of less than 5%. The tape can have a flexible backing such as a low-adhesion carrier web which can be stripped off from a piece of the tape that has been applied to a microwave food package, or when the backing is heat-resistant, it can be left in place.

A pressure-sensitive adhesive comprises a moisture-curable polymer comprising a polymer prepared by polymerization of at least one .alpha.-olefin monomer, said polymer containing hydrolyzable or condensable silyl groups and having a weight average molecular weight of at least 30,000. The pressure-sensitive adhesive can be hot-melt coated without emitting volatiles and then can adhere aggressively to both polar and nonpolar substrates. The PSA has good internal strength at high temperatures.
