Abstract: Disclosed herein are microporous films comprising polymer blends comprising at least two polymers and a compatibilizer. The films may also comprise at least one ethylene/?-olefin interpolymer and two different polyolefins which can be homopolymers. The ethylene/?-olefin interpolymers are block copolymers comprising at least a hard block and at least a soft block. In some embodiments, the ethylene/?-olefin interpolymer can function as a compatibilizer between the two polyolefins which may not be otherwise compatible. Methods of making the polymer blends and microporous films made from the polymer blends are also described.

Abstract: The invention is a process for bonding glass to a substrate without the need to prime the surface of the substrate. The process comprises, first, treating the surface of the substrate with air plasma, applying to the surface of the substrate or to the surface of the glass an adhesive capable of bonding to the treated substrate and glass, and contacting the glass and the substrate with the adhesive disposed between the substrate and the glass, and allowing the adhesive to cure. Preferably the substrate is coated with a coating. Preferred adhesives are polyurethane or silane functional elastomeric adhesives. The process of the invention allows bonding of glass to a substrate without the need to use a primer on the substrate prior to application of the adhesive. The process is especially effective in facilitating the bonding of glass to coated substrates, especially substrates coated with acid resistant coatings such as PPG's carbamate coating or DuPont's Gen III, IV and VI coatings.
