Description
В ОСНОВНОМ авт. св. .Nb 136557 описан способ получени привитых белковополиэфиракрилатных пленкообразующих материалов путем перемешивани алкилакрилатов и белкового компонента при повышенной температуре в щелочной среде в присутствии перекисных агентов. Однако получаемые пленки не обладают устойчивостью к воздействию низких температур. При температуре - 3° они тер ют эластичность.BASIC Auth. St. .Nb 136557 describes a method for preparing grafted protein-polyether acrylate film-forming materials by mixing alkyl acrylates and the protein component at elevated temperature in an alkaline medium in the presence of peroxide agents. However, the resulting films are not resistant to low temperatures. At a temperature of –3 °, they lose their elasticity.
Предлагаемый способ отличаетс тем, что используют смесь метили бутилакрилатов с содержанием последнего 30-60% с последующим взаимодействием этой смеси с белковым компонентом в соотношении 0,,5-1 соответственно и дальнейшей обработкой способом по авт. св. № 136557. Это позвол ет придать пленкам морозоустойчивость.The proposed method is characterized in that a mixture of methyl butyl acrylates is used with the content of the latter 30-60%, followed by the interaction of this mixture with the protein component in a ratio of 0, 5-1, respectively, and further processing by the method of ed. St. No. 136557. This allows the films to be frost resistant.
При осуществлении способа в смесь, состо щую из белка и полиэфиракрилатов , добавл ют аммиак, надсернокислый калий и перемешивают массу при 87-97°.In the process, ammonia, potassium sulphate are added to a mixture of protein and polyether acrylates, and the mass is stirred at 87-97 °.
Пример 1. К 1000 мл 15%-ного раствора казеина добавл ют при перемешивании 500 мл 2,5%-ного раствора аммиака, 9 г надсернокислого кали , 1700 мл воды, 150 мл метилакрилата, 150 мл бутилакрилата и перемешивают при температуре 20-25° в течение 10 мин. Нагревают реакционную смесь до 95-98° и перемешивают при этой температуре 30-40 мин (до исчезновени запаха мономеров).Example 1. To 1000 ml of a 15% casein solution is added with stirring 500 ml of a 2.5% ammonia solution, 9 g of potassium sulphate, 1700 ml of water, 150 ml of methyl acrylate, 150 ml of butyl acrylate and stirred at 20-25 ° for 10 min. Heat the reaction mixture to 95-98 ° and stir at this temperature for 30-40 minutes (until the odor of the monomers disappears).
Продукт реакции - устойчивый раствор, неограниченно смешивающийс с водой. При высыхании образует пленки с раст жением в момент разрыва до 200-250%. Эластичность пленок сохран етс при температуре - 25°.The reaction product is a stable solution that is indefinitely miscible with water. On drying, it forms films with stretching at the moment of rupture up to 200-250%. The elasticity of the films is maintained at a temperature of -25 °.
