Description
Известен способ получени водостойких поливинилспиртовых волокон и пленок введением в раствор поливинилового спирта (ПВС) людифицирующих добавок, последующим формованием и термической обработкой.A known method of producing water-resistant polyvinyl alcohol fibers and films by introducing into a solution of polyvinyl alcohol (PVA) people-specific additives, followed by molding and heat treatment.
С целью придани ионообменных свойств и кислотостойкости издели м из ПВС предлагаетс вводить в его раствор инициатор, например перекись водорода, и акриловую кислоту в качестве модифицирующей добавки. Количество акриловой кислоты, вводимой в раствор ПВС, составл ет 20-30Vo веса полимера , а количество инициатора - 20/0 веса акриловой кислоты.In order to impart ion exchange properties and acid resistance to PVA products, it is proposed to introduce into its solution an initiator, for example hydrogen peroxide, and acrylic acid as a modifying additive. The amount of acrylic acid added to the PVA solution is 20-30Vo polymer weight, and the amount of initiator is 20/0 weight acrylic acid.
Пример 1. В раствор ПВС добавл ют акриловую кислоту в количестве 2о/о веса полимера и перекись водорода в количестве 200/0 веса кислоты. Отлитые из этого раствора пленки подвергают термической обработке при 220°С в течение 5 мин.Example 1. Acrylic acid in an amount of 2 ° / about weight of polymer and hydrogen peroxide in an amount of 200/0 weight of acid are added to the PVA solution. The films cast from this solution are heat treated at 220 ° C for 5 minutes.
Полученные пленки обладают следующими свойствами: растворимость их при кип чении в течение часа в воде не более 2о/о (растворимость пленок без добавок, термически обработанных в тех же услови х, более 60о/о); набухаемость в воде при 20°С в течение 30 мш-1 50Э/0 (набухаемость пленок без добавок , термически обработанных в тех же услови х , 24Vo); пленки не раствор ютс при 4-часовом кип чении в 20/о-ной HgSOj (пленки без добавок раствор ютс полностью); ионообменна способность 1,5-2 мг-экв/г.The films obtained have the following properties: their solubility during boiling for an hour in water is not more than 2 ° / o (the solubility of films without additives thermally treated under the same conditions, more than 60 ° / o); swelling in water at 20 ° C for 30 msh-1 50E / 0 (swelling of films without additives thermally treated under the same conditions, 24Vo); the films do not dissolve at 4-hour boiling in 20 / o. HgSOj (films without additives dissolve completely); ion exchange capacity 1.5-2 mg-eq / g.
Пример 2. Из раствора поливинилового спирта с добавкой ЗОэ/о акриловой кислоты пр дут волокно по сухому методу формовани . Его подвергают термической обработке при 220°С в течение 5 мин. Усадка волокна при кип чении составл ет не более Юэ/о- Волокно не раствор етс , в 20о/о-ной naSOi при кип чении. Ионообменна способность 1,5- 2 мг-экв/г.Example 2. From a solution of polyvinyl alcohol with the addition of SOA / o acrylic acid, the fiber is spun using a dry forming method. It is subjected to heat treatment at 220 ° C for 5 minutes. The shrinkage of the fiber during boiling is no more than Yue / o. The fiber does not dissolve, in 20 ° / oh NaSOi during boiling. Ion exchange capacity 1.5–2 mg-eq / g.
