19 Claims

1. A photopolymerizable compound comprising:

a polyaxial central core (CC) and 2-4 arms of the formula (A)-(B) or (B)-(A) extending from the central core,

where

at least one of the arms comprises a light-reactive functional group (Q) comprising a thiol group, an acrylate group, or a methacrylate group,

(A) is the ring-opening polymerization product from a monomer selected from trimethylene carbonate (T) and caprolactone (CAP), and

(B) is the ring-opening polymerization product of a monomer of at least one of glycolide, lactide, or p-dioxanone.
