Abstract
The present disclosure relates to degradable polymers which contain a hydrophobic and hydrophilic segment which is sensitive to pH. In some aspects, the polymers form a micelle which is sensitive to pH and have backbones which are capable of undergoing degradation in vivo. In some aspects, the disclosure also provides methods of using these degradable polymers for the delivery of a drug.
