The surface and adhesive properties of isotactic polypropylene (iPP) grafted by maleic anhydride (MA) have been investigated. The attention has been paid to the analysis of the change in hydrophilicity as well as to the interfacial equilibrium and me

A much more efficient formation of crosslinks was observed in the free-radical polymerization of dodecyl methacrylate with respect to the amount of decomposed peroxide than it would correspond to the additional peroxide crosslinking of formed poly(do
