摘要： A polyvinylacetal resin powder with a low metal content, being excellent in transparency, moisture resistance and electrical insulating properties and having a large specific surface area, and a process for its production, are presented. A polyvinylacetal resin powder obtained by reacting polyvinyl alcohol and an aldehyde in the presence of an acid catalyst, which has an acetalization degree of at least 60 mol%, a specific surface area of from 1.50 to 3.50 m /g, a bulk density of from 0.12 to 0.19 g/cm , an average particle diameter of from 0.5 to 2,5 mu m and a metal content of at most 80 ppm. It is produced, for example, by feeding a reaction fluid containing polyvinyl alcohol, an aldehyde and an acid catalyst into a first reactor, to carry out an acetalization reaction, discharging the reaction fluid wherein the acetalization degree has reached from 10 to 60 mol%, and feeding the same into a second reactor to carry out a further reaction to bring the acetalization degree of polyvinylacetal to at least 65 mol%.

The intermediate film for laminated glass according to the present invention has a layered structure including at least two layers, comprising: a first layer containing a polyvinyl acetal resin and a plasticizer; and a second layer positioned on a first surface of the first layer. In a phase diagram of three values including a degree of acetalization, a degree of acetylation, and a hydroxy group content of the polyvinyl acetal resin contained in the first layer, the values of the degree of acetalization, the degree of acetylation, and the hydroxy group content each fall within a region surrounded by a line including four straight lines connecting a first coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 70 mol%: 30 mol%: 0 mol%), a second coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 34 mol%:30 mol%:36 mol%), a third coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 94 mol%: 0 mol%:6 mol%), and a fourth coordinate (degree of acetalization:degree of acetylation:hydroxy group content = 100 mol%: 0 mol%: 0 mol%) in the stated order.
