ート、繊維等の成形物に特異な性質を与え３種々の用途
に展開されている。Low refractive index and excellent weather resistance. Because it has properties such as flame retardancy, it imparts unique properties to molded products such as films, sheets, and fibers that are obtained from it, and is used for a variety of purposes.
しかし、 ｐｖ叶底成形物物性、特に強度を十分にする
には高分子量のものを使用する必要があり。However, it is necessary to use a material with a high molecular weight in order to obtain sufficient physical properties, especially strength, of the PV molded product.
■溶融粘度が著しく高くなって、流動性が低下し。■The melt viscosity becomes significantly high and the fluidity decreases.
成形物表面に凹凸が発生しやすいこと、■流動性を上げ
るべく成形を高温で行うと、Ｐｖ叶が分解し。Irregularities are likely to occur on the surface of the molded product. ■ If molding is performed at high temperatures to increase fluidity, Pv leaves will decompose.
有毒な弗化水素ガスを発生すること等の問題がある。There are problems such as generation of toxic hydrogen fluoride gas.

ないのが実状である。For this reason, various studies have been made to improve the moldability of Pv leaves.1 For example, according to Japanese Patent Publication No. 12012/1983, it is said that it is effective to blend polymethyl methacrylate, but this is not fully satisfactory. The reality is that we have not yet reached that stage.
