| titleOfInvention | Highly acetalized coarse granular polyvinyl acetoacetal |
| abstract | The object of the present invention is to obtain a degree of acetalization of more than 80 mol% and 100 μm obtained by acetalizing a partially or fully saponified polyvinyl ester having a degree of hydrolysis of 70 mol% or more with acetaldehyde. A highly acetalized coarse granular polyvinyl acetoacetal having the above average particle size, wherein the acetalization is introduced at a temperature T 1 of 0 ° C. ≦ T 1 ≦ + 20 ° C. and subsequently at a temperature T 2 above + 40 ° C. Highly acetalized coarse granular polyvinyl acetoacetal, characterized in that it is continued and in this case the temperature T 2 is maintained for 0.05 to 4 hours and the acetalization is carried out in a closed reactor It is. |
