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

The effects of monomer emulsion feed rates (R(a)) and (R/E)(E) values, the ratio of emulsifier amount between the initial charge (R) and the addition monomer emulsion (E), on the polymerization reaction features, the viscosities, surface tensions,particle sizes and particle sizes distributions of latexes, T-g and the insoluble fractions of films, the 180 degrees peel strength, tack and holding power of pressure-sensitive adhesive (PSA) tapes, prepared from the latexes, were studied. Experimental study shows that the grafting and crosslinking fraction in the PSA tapes must be controlled within a suitable range to keep the balance of the 180 degrees peel strength, tack and holding power.展开更多
