摘要

A cyclic carbonate monomer has the formula (2): wherein i) t and t′are integers independently having a value from 0 to 6 wherein t′and t cannot both be zero, ii) each Q1 is a monovalent radical independently selected from the group consisting of hydrogen, halides, alkyl groups comprising 1 to 30 carbons, and aryl groups comprising 6 to 30 carbon atoms, iii) L′is a divalent linking group comprising one or more carbons, and iv) S′is a steroidal group.
