| abstract |
The invention includes an interlayer film and composition comprising a polymer composition obtainable from (a) at least one low crystallinity propylene polymer, and at least one (b) internal adhesion enhancer, (c) at least one clarity enhancer or (d), more preferably, both (b) and (c). The invention also includes a process of preparing a film comprising (a) supplying at least one first component, a low crystallinity propylene polymer, (b) supplying at least one second component, selected from at least one an internal adhesion enhancer, at least one clarity enhancer or a combination thereof; and, (d) admixing the first and second components and optional additives. Additionally, the invention includes a process of making a laminate comprising steps of (a) positioning at least one layer of the interlayer film directly adjacent to at least one layer of substrate (b) applying sufficient heat or other energy to result in softening of the interlayer directly adjacent the substrate with simultaneous application of sufficient pressure to press polymer into intimate contact with substrate. The invention also includes laminates and articles comprising the composition or film of the invention or a combination thereof. |
