Photoactive additives containing siloxane
Abstract:
Photoactive additives are disclosed. Such additives are polymers or oligomers that contain UV-active groups (such as ketone groups) and contain polysiloxane blocks as well. When added to a base polymeric resin and used in molding, this structure promotes migration of the additive to the surface. Crosslinking occurs upon exposure to ultraviolet light.
