| titleOfInvention |
Vinyl alcohol copolymers, water-soluble films containing them and their use as packaging material and manufacturing process thereof |
| abstract |
The description relates to vinyl alcohol copolymers, which can be produced by the acid-catalysed acetalisation reaction of polyvinyl alcohols with a degree of saponification of 80 - 99.5 mol. % and preferably between 88 and 99.5 mol. % with natural substances or their derivatives containing carbonyl or presumptive carbonyl groups. The description also relates to water-soluble films containing such vinyl alcohol copolymers, the solubility of which can be adjusted to the desired solution temperature. Said water-soluble films are used as packaging materials and auxiliaries, e.g. in the form of sealing lacquers. |
