The use of precursor polymers to prepare new excipients

Polymers are ubiquitous excipients in medicines and are widely used in drug delivery systems. To address the need for novel polymers that can enhance the properties of formulations, narrow molecular weight distribution precursor polymers are used to prepare candidate polymers for a range of pharmaceutical applications. Both a homopolymer and block copolymer precursor were utilised in this study to give functional polymers. Thiomers were prepared from the homopolymer precursor and latently hydrophilic block copolymers were prepared from the copolymer precursor.
