TRANSPARENT COMPOSITIONS AND LAMINATES

摘要

The invention includes an interlayer film and composition comprising a po lymer composition obtainable from (a) at least one low crystallinity propyle ne polymer, and at least one (b) internal adhesion enhancer, (c) at least on e clarity enhancer or (d), more preferably, both (b) and (c). The invention also includes a process of preparing a film comprising (a) supplying at leas t one first component, a low crystallinity propylene polymer, (b) supplying at least one second component, selected from at least one an internal adhesi on enhancer, at least one clarity enhancer or a combination thereof; and, (d ) admixing the first and second components and optional additives. Additiona lly, the invention includes a process of making a laminate comprising steps of (a) positioning at least one layer of the interlayer film directly adjace nt to at least one layer of substrate (b) applying sufficient heat or other energy to result in softening of the interlayer directly adjacent the substr ate with simultaneous application of sufficient pressure to press polymer in to intimate contact with substrate. The invention also includes laminates an d articles comprising the composition or film of the invention or a combinat ion thereof.
