| titleOfInvention | Polyvinyl acetal and interlayer film for laminated glass containing the same |
| abstract | Polyvinyl acetal having an acetalization degree of 40 to 90 mol%, a vinyl ester monomer unit content of 0.1 to 20 mol%, and a viscosity average polymerization degree of 200 to 5000, When the polyvinyl acetal heated at 230 ° C. for 3 hours was measured by gel permeation chromatography, the peak top molecular weight (A) measured by a differential refractive index detector and an absorptiometric detector (measurement wavelength 280 nm) were measured. The peak top molecular weight (B) is expressed by the following formula (1) (AB) / A <0.60 (1) And a polyvinyl acetal having an absorbance at a peak top molecular weight (B) of 0.50 × 10 −3 to 1.00 × 10 −2 . Thereby, the polyvinyl acetal which can obtain the film with few coloring by heating and few foreign substances (undissolved part) can be provided. |
