  Polymers comprising a polymer backbone comprising one or more degradable units are described. The polymer may additionally comprise two or more polymer segments comprising radically (co)polymerizable vinyl monomer units. The degradable units may be independently selected from, but not limited to, at least one of hydrodegradable, photodegradable and biodegradable units between the polymer segments and dispersed along the polymer backbone. The degradable units may be derived from one or more monomers comprising a heterocyclic ring that is capable of undergoing radical ring opening polymerization, a coupling agent, or from a polymerization initiator, radically polymerizable monomers, as well as other reactive sources. Embodiments of the degradable polymer of claim are capable of degrading by at least one of a hydrodegradation, photodegradation or biodegradation mechanisms to form at least one of telechelic oligomer and telechelic polymeric fragments of the polymer. The degradable polymer may be able to degrade into polymer fragments having a molecular weight distribution of less than 5, or in certain applications it may be preferable for embodiments of the polymer to be capable of forming polymer fragments having a molecular weight distribution of the polymer fragments less than 3.0 or even less than 2.5. Embodiments of the present invention also include methods of producing degradable polymers.

  本发明涉及一种聚合物，其聚合骨架包含一个或多个可降解单元。该聚合物可能还包括两个或更多聚合物片段，其中包括自由基（共）聚合性乙烯单体单元。可降解单元可以独立选择，但不限于，在聚合物片段之间和沿聚合物骨架分散的至少一种水解降解、光降解和生物降解单元。可降解单元可以来源于一个或多个单体，包括能够经历自由基开环聚合的杂环环、偶联剂或聚合引发剂、自由基聚合性单体以及其他反应源。该可降解聚合物的实施例能够通过至少一种水解降解、光降解或生物降解机制降解，形成聚合物的末端寡聚物和末端聚合物片段。该可降解聚合物可以降解成分子量分布小于5的聚合物片段，或在某些应用中，最好是实施例能够形成分子量分布小于3.0甚至小于2.5的聚合物片段。本发明的实施例还包括制备可降解聚合物的方法。
