Creep of St-Mba-Ma polymers under microindentation

The deformation, temperature and time dependences of the STBMAMA copolymer have been studied; the relationship between creep and microhardness has been found. The results of ampicillin grafting onto the copolymer have been described; the effect on mechanical properties has been shown. Studies of t...
