| 摘要 |
The invention relates to a system employed as a matrix for producing sensors or biomaterials. According to the invention, the system is obtained by the reaction of copolymerization of a spiro-orthoester with 2-hydroxyethyl methacrylate, in the presence of a radical initiator, a surface-active agent of the sodium lauryl sulphate type and a protective colloid of the polyvinyl alcohol type, to finally result in an aqueous dispersion copolymer which is sensitive to temperature and pH. |
