Abstract
A method for preparing blends of at least two polymer components is described herein. The disclosed method generally involves controlling relative molecular weights and ratios of the two or more polymer components by selecting a first initiator, a second initiator, and a monomer, and subjecting the reactants to conditions suitable to polymerize the monomer based at least in part on the first and second initiators in connection with obtaining the polymeric blend. The second initiator is advantageously selected based on one or more characteristics associated therewith, based on a characteristic of the first initiator. A polymeric blend produced according to such a method is also provided herein.

A method for obtaining a bioabsorbable polymer blend comprising at least two bioabsorbable polymer components, comprising:
- controlling relative molecular weights of the at least two bioabsorbable polymer components and one or more ratios of the at least two bioabsorbable polymer components by selecting a plurality of reactants, the reactants comprising:
- a first initiator;
- a second initiator, wherein a first value associated with the second initiator is selected based at least in part on a first value associated with the first initiator;
- and
- a first monomer;
- and
- polymerizing the first monomer based at least in part on the first initiator and the second initiator in connection with obtaining the bioabsorbable polymer blend,
- wherein one of the first initiator and the second initiator is a small molecule initiator and the other of the first initiator and the second initiator is a macroinitiator.
