THERMOPLASTIC POLYOLEFIN COPOLYMER LAMINATION FILM, LAMINATED STRUCTURES AND PROCESSES FOR THEIR PREPARATION
摘要
Disclosed are polyolefin copolymer films comprising alkoxysilane groups and a catalyst for crosslinking the alkoxysilane groups; wherein the crosslinking catalyst is a Lewis or Bronsted acid or base compound that has a relatively high melting point and therefore initiates the crosslinking essentially only at the lamination temperature, preferably at or above at least 50° C. Also disclosed are films wherein (i) the layer or layers comprising the alkoxysilane groups, including surface layer(s), comprise the crosslinking catalyst; or (ii) layer or layers comprising alkoxysilane groups do not contain crosslinking catalyst and have a facial surface in adhering contact with a layer of a thermoplastic polyolefin copolymer comprising the crosslinking catalyst; or (iii) there is a combination of layers (i) and (ii). Also disclosed are laminated glass structures and processes for their preparation that employ such films. The disclosed laminate structures include safety glass and photovoltaic modules.
