- these plastics plate coating materials often contain an ultraviolet absorber, and have the same problems as the above-mentioned film containing the ultraviolet absorber.
- ETFE copolymer films have been proposed as agricultural coating materials because of their excellent properties such as heat resistance, weather resistance, light transmittance, and non-adhesion. Have been.
- ETFE copolymer films are used in view of their non-adhesiveness and heat resistance. Even in this case, the conventional ETFE copolymer has a problem that the tensile modulus is large and the followability to a substrate having a complicated shape is low.
- the conventional ETFE copolymer is preferable as an interlayer film for laminated glass used for safety glass, etc., because it has a high light transmittance and the like, but 3 (has a large elastic modulus, it is difficult to adhere to glass, and processing is difficult. Difficult to handle, absorbs bite when glass breaks Sex was not enough.

This is considered to be due to the crystallinity of the copolymer and the effect of internal plasticization.
- the ratio of the polymerized unit based on tetrafluoroethylene and the polymerized unit based on ethylene is ⁇ / ⁇ (molar ratio). If the ratio of both is not in this range, for example, if it is smaller than 35/65, the fluorine content is small and the weather resistance is insufficient. On the other hand, when the ratio is larger than 65 to 35, haze based on the crystalline part is generated, and the transparency is reduced, and none of the objects of the present invention can be achieved.

Among them, a solution polymerization power of 3 'is preferable because the composition of the obtained copolymer can be easily controlled uniformly.
- the produced ETFE copolymer is formed into a film by a known method such as an inflation method or an extrusion method. If the thickness of the film is too thin, it tends to break, and if it is too thick, it is inconvenient for cutting, bonding, spreading, etc., and the light transmittance is reduced.
