In Vivo Degradation Mechanisms of Aliphatic Polycarbonates and Functionalized Aliphatic Polycarbonates

Area of Science:

• Polymer Science
• Biomaterials Science
• Organic Chemistry

Background:

• Aliphatic polycarbonates (APCs) are polymers studied for decades.
• APCs are less utilized than aliphatic polyesters in biomaterials.
• Functionalized APCs can be synthesized, increasing interest.

Purpose of the Study:

• To review in vivo degradation mechanisms of APCs and functionalized APCs.
• To provide guidance for developing APCs as biomaterials.
• To address the variability in APC degradation.

Main Methods:

• Literature review of studies on aliphatic polycarbonate degradation.
• Analysis of degradation pathways in biological environments.
• Examination of structure-property relationships influencing degradation.

Main Results:

• APC degradation is dependent on specific structural and molecular weight factors.
• Degradation to diols and carbon dioxide is not universally observed.
• Functionalization can influence APC degradation profiles.

Conclusions:

• Understanding APC degradation mechanisms is crucial for biomaterial design.
• Further research is needed to ensure predictable degradation for applications.
• APCs offer potential for drug delivery and tissue engineering if degradation is controlled.
