MetadataShow full item record
Novel type of crosslinkable polymeric photoinitiators with hyperbranched architecture were synthesized and characterized. This type of UV curable hyperbranched urethane acrylates utilizes xanthate groups for photoinitiation and controlled crosslinking. A series of polymers were synthesized with different types of functionalization by varying type of the hydroxyl alkyl (meta)acrylates. Obtained polymers have low viscosities and high molecular weights. Glass transition temperatures of crosslinked samples were surprisingly high for their chemical compositions.
