Указанный сополимер может быть использован в виде пленок или покрытий в химической промышленности или в медицине.The specified copolymer can be used in the form of films or coatings in the chemical industry or in medicine.

Целью изобретени   вл етс  упрощение технологии выделени  полиси- локсанкарбонатов общей формулы 1.The aim of the invention is to simplify the technology for the isolation of polysiloxane carbonates of general formula 1.

Пример 1. 50 мл 15%-ного раствора полисилоксанкарбоната в хлористом метилене при перемешивании добавл ют в 150 мл нерастворител  содержащего 142,5 мл ацетона и 7,5 мл (5 об.%) воды. Сополимер высаживаетс  в виде мелкодисперсного некомкующегос  порошка, которыйExample 1. 50 ml of a 15% solution of polysiloxane carbonate in methylene chloride are added with stirring to 150 ml of a non-solvent containing 142.5 ml of acetone and 7.5 ml (5% by volume) of water. The copolymer is precipitated in the form of a fine, non-combustible powder, which

отдел ют фильтрованием и сушат при 60 С в течение 2,5 ч до посто нной массы. Выход 14 г (80% от теоретического ) ; 0,22 (в хлористом метилене при 25 °С) .is filtered and dried at 60 ° C for 2.5 hours to constant weight. Yield 14 g (80% of theoretical); 0,22 (in methylene chloride at 25 ° C).

Аналогичным способом провод т выделение остальных полисилоксан- карбонатов общей формулы 1, свойства которых приведены в таблице.In a similar way, the remaining polysiloxane carbonates of general formula 1 are isolated, the properties of which are listed in the table.

Как следует из данньк, представ- ленных в таблице, при выделении полисилоксанкарбонатов согласно прелагаемому способу целевые продукты представл ют собой мелкодисперсные, неагломерирующиес  порошкообразные вещества, что позвол ет значительно упростить технологию их выделени .As follows from the data presented in the table, when isolating polysiloxane carbonates according to the proposed method, the target products are finely dispersed, non-agglomerated powdered substances, which makes it possible to significantly simplify the technology of their isolation.
