Abstract
ABSTRACT Degradable polyester materials are widely utilized in medicine as resorbable sutures, implantable devices, and drug delivery. These applications require precise and tunable degradation control; predictable number-average molecular weight ( M̅ n ), narrow polydispersity (PDI), and diverse material properties define polyester utility, which are not easily achieved through well-established synthesis approaches. Ring-opening copolymerization (ROCOP) provides reproducible M̅ n control, narrow PDI, and expands monomer diversity. In this work, poly(cyclohexene succinate) (PCS) and poly(propylene succinate) (PPS) were synthesized through a central composite design of experiments approach, systematically varying anhydride:epoxide ratio, monomer:catalyst ratio, reaction temperature, and reaction time. Reduced synthesis factor-response models explained significant variation for all characterized properties relevant to degradation control. PCS and PPS readily degraded under base-catalyzed hydrolysis conditions with significantly higher mass loss in PPS materials compared to PCS, highlighting the monomer selection influence in degradation behaviour. These findings highlight the potential for ROCOP to generate degradable biomaterials with reproducible material properties in application-specific biomedical use.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
