PROCESS FOR EXTRUSION OF PLASTICIZED PVB FILM WITH REDUCED PLATE-OUT OF ADHESION CONTROL AGENT RESIDUES |
| 摘要 |
The invention is directed to a process for extrusion of mixtures comprising at least one polyvinyl acetal, at least one plasticiser and least one earth alkaline salt of a carboxylic acid, wherein 0.001%-1 wt. % (based on the combined weight of PVB resin and plasticizer) of at least one organic acid having 4 to 30 carbon atoms is added to the mixture. |
