Abstract
The introduction of methacrylic, carboxylic and phosphate functional groups on the core and at the end of the poly(ethylene oxide) (PEO) arms in the PEO star-shaped polymers is described. In the polyglycidol (PGL) star-shaped polymers phosphate groups were attached to the PGL arms as side groups. Polymers were characterized by NMR and SEC analysis with triple detection. The conversion of the unsubstituted star-shaped polymers into functionalized has been confirmed by 1H and 13C NMR spectra. The influence of the length of arms, their structure and the presence of functional groups on melting (Tm) and crystallization (Tc) temperatures and the degree of crystallinity (Xc) by differential scanning calorimetry (DSC) has been studied.
