造法に関するものである。The present invention focuses on the fact that when polyvinyl pyridine absorbs moisture, the glass transition temperature Tg ("C) drops extremely to below room temperature. After polyvinyl pyridine absorbs moisture to an appropriate degree and has plasticity, it is stretched. The present invention relates to a method for producing a polyvinylpyridine film having high rigidity and flexibility.

溶融法を用いてフィルム化することも可能となる。However, when polyvinyl pyridine is impregnated with water, glycerin, ethylene glycol, etc., the transition temperature Tg is extremely lowered, so it is also possible to form a film using a semi-melting method in which a plasticizer is added and extrusion molded. becomes.
またポリビニールピリジンをアルコール類の溶媒で溶解

ずれかの方法を用いる。The stretching method is 5 to 2 times from the beginning in an atmosphere of 40°C or higher.
The water content of the film can be reduced by stretching a film containing 0 weight of water 1 to 5 times uniaxially, or biaxially stretching 1 to 3 times each, or by blowing steam into an atmosphere at 40°C or higher. One of the following methods is used: stretching the film to a weight of 5 to 20%.
すなわち吸湿させた後延伸することも吸湿させながら同
時に延伸することも可能である。That is, it is possible to stretch the film after absorbing moisture, or to simultaneously stretch it while absorbing moisture.
