Polytetramethylene adipate polyol PTMA

Core-shell PU NPs can also be prepared by appropriate choice of isocyanate [166]. Blocked amphiphilic prepolymers were prepared by Cheong et al., where the hydrophobic block is composed of IPDI-polytetramethylene adipate polyol (PTMA) and the hydrophilic block is MDI-DMPA. The resulting polymer is added drop-wise to water under stirring, resulting in a core-shell structure with the hydrophobic IPDI-PTMA in the core and hydrophilic MDI-DMPA in the shell (80-100 nm diameter) [166].
