In our previous two works we were mainly concerned with the synthesis and polymerization of two types of new bioactive acrylic esters: 3-acrylato-4-oxo-3, 4-dihydro-1, 2, 3-benzotriazines and N-p-acryloxtobenzoyloxysu...In our previous two works we were mainly concerned with the synthesis and polymerization of two types of new bioactive acrylic esters: 3-acrylato-4-oxo-3, 4-dihydro-1, 2, 3-benzotriazines and N-p-acryloxtobenzoyloxysuccinimides and the use of the latter copolymer for the immobilization of serum protein.展开更多

Both catalysts were used to synthesize random and block high molecular weight copolymers which were further hydrogenated using a Wilkinson’s catalyst. Then, the saturated copolymers were modified by reacting with sodium 4-hydroxybenzene-sulfonate dihydrate to generate new ionomers with fluoro-sulfonic acid pendant groups.展开更多
