Description

Известно получение смол на основе ноливиинлового спирта в среде растворителей.It is known to obtain resins based on noliviilovogo alcohol in the environment of solvents.

Предлагаемый способ получени  поливинилацеталей оспован на реакции между поливиниловы: спиртом и а:п-;ил-или арил-виииловыли-, а также тиовиниловыми простыми эфирами .The proposed method for the preparation of polyvinyl acetals is based on the reaction between polyvinyl alcohol: a and p, yl, or aryl-viyl, and pyrolysis of thiovinyl ethers.

Синтез смол осуи1.сств.1 стс  в среде хлорированных растворителей в присутствии сол ной кислоты в качестве ьатализатора при нагревании до 60 или без нагревани .Synthesis of resins of Oxy1. Cwc 1 cc in an environment of chlorinated solvents in the presence of hydrochloric acid as a catalyst when heated to 60 or without heating.

П р и м е р 1. 4.4 в. ч. поливинилового спирта ст 1ешивают с 7,2 в. ч. винилэтилового эфира и смесь выдерживают без нагревани  в среде дихлорэтана в присутствии сол ной кислоты с уд. в. 1.15 -1.19 (до Зъ }; весу исходных реагентов) при посто ином перемешивании до получени  однородной и прозрачной .дшссы. Полученный продукт выливают в воду , нейтрализуют ам1 и1аком. промывают теплой водой и высушивают при нормалг ной тe нlepaтype.PRI me R 1. 4.4. including polyvinyl alcohol st. including vinyl ethyl ether and the mixture is kept without heating in dichloroethane in the presence of hydrochloric acid with beats. at. 1.15 -1.19 (up to 3g); weight of the initial reagents with constant stirring until a homogeneous and transparent volume is obtained. The resulting product is poured into water, neutralized with amyl. Wash with warm water and dry with normal teplate.

Пример 2. 4,4 в. ч. поливинилового спирта. 13,2 в.ч. винилфенилового эфира нагревают нри 50 при перемешнваннн в среде днхлорэтана в присутствни 3:: сол ной кислоты уд. в. 1,15-1,19. Полученную массу нейтралнзуют. про: И11вают и сушат .Example 2. 4.4 c. including polyvinyl alcohol. 13.2 incl. The vinylphenyl ether is heated at 50 with stirring in dichloroethane in the presence of 3: hydrochloric acid beats. at. 1.15-1.19. The resulting mass is neutralized. Pro: I11vayut and dried.

Полученные смолы хорошо раствор ютс  в ацетоне, снирте, циклогексаионе и других растворител х.The resultant resins are well soluble in acetone, decal, cyclohexaione and other solvents.

Преимущество предлагаемого способа состоит в использовании новых видов сырь  дл  получени  смол на основе полнвиннлового спирта.The advantage of the proposed method is the use of new types of raw materials for the production of resins based on quinous alcohol.

Способ дает воз; южность получать продукты с высокой степенью за: 1ещени  гидроксильных грунп поливинилового спирта и исключает необходимость применени  при синтезе полнвинилацеталей ннзкокип щего альдегида.The method gives the cart; South to obtain products with a high degree of: 1) the hydroxyl prefabrication of polyvinyl alcohol and eliminates the need for the use of ncalk aldehyde in the synthesis of full vinyl acetate.
