Abstract

According to the present invention, a polyvinyl alcohol film that contains polyvinyl alcohol satisfies expressions (1) and (2) when X (nm) is the average value of the lamellar crystal thickness of the polyvinyl alcohol as found by small-angle x-ray measurement when the polyvinyl alcohol film is immersed in pure water that is at 25°C and Y (nm) is the average value of the lamellar crystal thickness of the polyvinyl alcohol as found by small-angle x-ray measurement when the polyvinyl alcohol film is in air that is at a temperature of 25°C. Using such a polyvinyl alcohol film to produce a polarizing film makes it possible to reduce folding at the ends of the film during the first half of a stretching step and breakage of the film during the second half of the stretching step and efficiently obtain a polarizing film.

Abstract

Provided is a method for producing a vinyl ester-based copolymer comprising: polymerizing a composition comprising (i) vinyl ester, and (ii) vinyl monomer with a boiling point of 100°C or higher to produce a copolymer paste, wherein the vinyl ester has a lower boiling point than the vinyl monomer (polymerization step), removing the vinyl ester from the copolymer paste (removing step), evaporating the vinyl monomer in an evaporator by heating the copolymer paste at a pressure of less than 1 atm (evaporation step), and discharging the copolymer paste having a viscosity of 8000 cP or more from the evaporator. By this method, unreacted vinyl monomer remained in the copolymer paste can be recovered effectively.

Abstract

The present invention relates to a laminate structure comprising a composite adhesive polymeric interlayer (CAPI) comprising at least two layers: (i) a submicron-thick superbonding layer and/or a top adhesive polymeric interlayer (TAPI) and (ii) a bulk adhesive polymeric interlayer (BAPI). If the TAPI is present, it comprises cohesive substantially discrete and/or continuous debonding zones. Such debonding zones are located preferably within the 10% thickness of CAPI from the interface of said CAPI and the glass substrate. These zones allow for a unique combination of modified API-glass debonding, laminate toughness, and laminate durability. Various spatial patterns and densities of debonding are described, as well as the resulting material properties.
