Crosslink nature in Cr(III)-polyacrylamide gels
Vamvakaki, Maria; Yamasaki, E. N.; Hadjiyannakou, Stella C.; Patrickios, Costas S. (2001)The equilibrium constants of various candidates for the crosslinking reaction between chromium(III) and partly hydrolysed polyacrylamide have been calculated. For this purpose use has been made of a) the crosslinking index ...

Synthesis and characterization of polyampholytic model networks: Effects of polymer composition and architecture
Demosthenous, Elena; Hadjiyannakou, Stella C.; Vamvakaki, Maria; Patrickios, Costas S. (2002)Synthesis and characterization of polyampholytic model networks were studied using group transfer polymerization (GTP). The degrees of swelling (DSs) of all the polyampholytic networks were also measured as a function of ...
