For this reason, gelatin was modified with reactive functional groups like vinyl groups, acetenyl groups, and thiol, and injectable gelatin hydrogel was fabricated by photoinitiated polymerization or click chemistry in previous research.
Finally, injectable composite hydrogel was obtained by photoinitiated polymerization in situ.
The method has previously been used for the study of the photoinitiated polymerization of HEMA by RF/TEoHa system in aqueous solution [20].
and then almost disappears for 60 s, indicating that the antifoulant CAP-A in the EMA-P antifouling coating doesn't hinder the formation of a crosslinking network through the photoinitiated polymerization of the C-C groups in EMA-P.
Recently, the thiolene photoinitiated polymerization has been the focus of many studies (12-14).

(13,14) The cationically photoinitiated polymerization has a longer living propagating species, which is referred to as "dark-cure." Epoxides, especially aliphatic epoxides, are one of the major materials for cationic initiated UV-curing technology.
The photoinitiated polymerization of acrylate resins is known to be strongly inhibited by oxygen which reacts rapidly with the initiator R* and polymer ([P*.sub.n]) radicals to generate inactive peroxy radicals:
In many photoinitiated polymerizations, the initiation rate is spatially inhomogeneous and there exists a gradient in polymerization rates (5-7) because the photoinitiator absorbs the radiation and so attenuates, the light intensity as a function of depth along the optical path.
