Polyvinyl acetal resin for thermoforming |
| abstract |
The purpose of the present invention to provide a polyvinyl acetal resin for thermoforming with which a molded article having excellent thermal stability and excellent thermal resistance can be obtained without sacrificing the characteristics of the polyvinyl acetal resin. The present invention relates to a polyvinyl acetal resin for thermoforming, the resin being obtained by acetalizing a polyvinyl alcohol resin having a viscosity-average degree of polymerization of 500-2,000 and a degree of saponification of 99.5 mol% or higher, the acetalization being performed using aldehydes, the total number of vinyl alcohol units acetalized with the aldehydes being 65-88 mol% relative to the overall number of repeating units, and the alkali metal content or alkaline earth metal content being 0.1-50 ppm. The molar ratio of the number of vinyl alcohol units acetalized with an aldehyde having four or more carbon atoms to the number of vinyl alcohol units acetalized with an aldehyde having three or fewer carbon atoms is preferably 90/10-0/100. |
