<p><P>PROBLEM TO BE SOLVED: To provide a coextrudable composition with PVDF, a coextruded film, and a base coated with the film in a state that the coextrudable composition is brought into contact with the base. <P>SOLUTION: The coextrudable composition with PVDF has a composition (total 100 pts.wt.) comprising P: 20-40 pts.wt. of PVDF, 40-60 pts.wt. of PMMA, 5-18 pts.wt. of an acrylic elastomer and 1-4 pts.wt. of an ultraviolet absorber. The coextruded film comprises (1) a layer (adhesion layer) of the coextrudable composition stuck directly and (2) a PVDF base layer (PVDF layer) comprising 50-100 pts.wt. of PVDF as the main component and 50-0 pts.wt. of PMMA. This PVDF layer consists of two layers of one layer which comes into contact with the coextrudable layer, comprises 50-90 pts.wt. of PVDF as the main component and 50-10 pts.wt. of PMMA and the other layer (outer layer) which comprises 75-100 pts.wt. of PVDF as the main component and 25-0 pts.wt. of PMMA. <P>COPYRIGHT: (C)2004,JPO</p> |
