Polyvinyl ester
| Polyvinyl ester - general formula - |
|---|
 (R = CH 3 ; CH 2 Cl; C 2 H 5 etc.) |
Polyvinyl among the thermoplastic plastics . Practically the most important representatives of this group of substances are polyvinyl acetate (PVAC) and polyvinyl propionate .
Manufacturing
The radical polymerization of vinyl ester 1 (e.g. vinyl acetate ; R = CH 3 ) yields polyvinyl ester 2 :
use
The transparent polymers are used in the production of paints and as adhesives . The hydrolytic cleavage of the ester bonds from vinyl acetate to polyvinyl alcohol is of technical importance.
