The development of new promising materials three-dimensional structure from available bioresorbable, biointegrable and biocompatible polymers is in demand relevant connection with the intensive regenerative medicine. In this work, hydrogels grafted copolymers methyl methacrylate/butyl acrylate onto a mixture collagen pectin were obtained during photocatalysis presence complex oxide RbTe 1.5 W 0.5 O 6 . characteristics synthesis products by gel penetrating chromatography, elemental analysis,...
Increasingly, scientists are turning to the study of marine, or fish, collagen, which is increasingly replacing collagen terrestrial animals, due fact that it hypoallergenic, since 96% identical human protein. Materials based on fish have a number advantages over their analogue animal origin: not carrier infectious diseases animals transmitted humans, has greater structural similarity provides higher level biocompatibility. copolymers with synthetic monomers promising. The use hybrid...
Butyl methacrylate copolymers with vinyl alkyl ethers and styrene have been obtained by compensate polymerization method. The properties of determined the use gel-penetration chromatography, IR- 1 H NMR-spectroscopy.
In order to obtain a graft copolymer of polybutyl acrylate (PBA) on the substratum emulsified fish collagen, RbTe1.5W0.5O6 complex oxide was used as photocatalyst under visible light irradiation (λ = 400–700 nm). The emulsion prepared by mixing monomer and aqueous collagen solution in ratio 1:2. Next, catalyst introduced into resulting mixture, followed stirring ultrasound treatment. Before reaction, bubbled with argon for 15 min. reaction carried out an flow continuous stirring. radiation...
The study of natural polymers is one the most advanced tasks modern chemistry. One these common polysaccharide pectin. Widespread acid hydrolysis was used to extract pectin from various substrates. Oxalic, citric and hydrochloric acids have been investigated for this purpose. water-soluble pectin-containing fraction extracted apples, sugar beet, lemon peel, pine needles. optimal condition heating substrate in a boiling water bath 1 hour with reflux solution (pH 2-3). We neutralized after...
A radical compensatory copolymerization of butyl acrylate with vinyl ether was carried out when the latter boiled in presence triethylboron. Under circumstances present system residual air oxygen acts as a co-initiator. As it turned out, boiling vinylbutyl amount is sufficient for oxidation triethylboron and copolymerization. Triethylboron from complex hexamethylenediamine isolated directly reaction medium by addition methacrylic acid two ways: together (method 1) or simultaneously before...
The copolymers of butyl acrylate with vinyl ether were synthesized by dosing the active monomer in presence an oxidizing agent and triethylboron isolated from complex hexamethylenediamine a solution adding methacrylic acid amount proportional moles to amine before introducing acrylate. was oxidized air oxygen remaining reaction mixture during boiling ether. carried out at varying times: 20 minutes, 40 minutes 60 then thermostated for some time. At end polymerization, liquid fraction...
Подобраны условия для осуществления компенсационной сополимеризации стирола и его аналогов: α-метилстирола стирохромтрикарбонила. Для процесса контролировали конверсию мономеров, состав строение сополимеров. Анализ сополимеров современными физико-химическими методами позволил установить преимущественно композиционно-однородное
