Verfahren zur Herstellung von Folien |
| 摘要 |
The invention relates to methods for producing films which in at least one layer contain fluoropolymers and poly(meth)acrylates. According to said methods first a mixture containing poly(meth)acrylate and fluoropolymers is prepared and said mixture is then processed into a film by extrusion of the mixture on a roll having a temperature </= 100 DEG C, preferably </=70 DEG C. The temperature of the mixture is kept below its gel temperature, during extrusion a filter is positioned upstream of the die inlet and the die temperature is maintained higher than the temperature of the mass entering the die but lower than the gel temperature of the mixture. Using the method provided for in the invention especially PVDF/PMMA films presenting high surface gloss and low clouding can be produced without the need for solvents or supporting films. |
