Description
Изобретение относитс к химии и технологии полимеров, а именно к способу получени полимерных гидрогелей , и может быть использовано в биологической и медицинской технике дл создани гидрогелевых сорбентов и устройств.The invention relates to polymer chemistry and technology, in particular, to a method for producing polymer hydrogels, and can be used in biological and medical technology to create hydrogel sorbents and devices.
Целью изобретени вл етс повышение водопроницаемости полимерных гидрогелей при сохранении их свето- прозрачности и прочности.The aim of the invention is to increase the permeability of polymeric hydrogels while maintaining their light transparency and strength.
Способ осуществл ют следующим образом.The method is carried out as follows.
Пример 1. 30 мае.ч. оксиэтил- метакрилата ОЭМ), 20 мае.ч. поли- И-винилпирролидона с мол.м. 11000± t 2000 (ПВП) и 0,2 мае.ч. персульфата кали (ПС) раствор ют в 99 мае.ч. воды, добавл ют к смеси 1 мае.ч. диметилсульфоксида (ДМСО) и полимери- зуют смесь до образовани гел межцу двум стекл нными пластинами с толщиной зазора:О,4 мм. Полученный в ви- де пленки гидрогель имеет характеристики , приведенные в таблице.Example 1. 30 ma.ch. hydroxyethyl methacrylate OEM), 20 ma.ch. poly-And-vinylpyrrolidone with mol.m. 11000 ± t 2000 (PVP) and 0.2 mach. Potassium persulfate (PS) is dissolved in 99 mash. water, is added to the mixture of 1 wt. dimethyl sulfoxide (DMSO) and polymerize the mixture before gel formation between the two glass plates with a gap thickness of about 4 mm. The hydrogel obtained as a film has the characteristics shown in the table.
