Abstract:
A method of preparing a polymer blend, said method comprising:a) providing a first polyacrylate component having an average molecular weight of more than 500,000 g/mol, said first polyacrylate component being selected from the group consisting of polyacrylates, polyacrylate copolymers, polyacrylate mixtures, and mixtures of polyacrylates and polyacrylate copolymers; and b) adding a second polyacrylate component having an average molecular weight of less than 500,000 g/mol to said first polyacrylate component to reduce the flow viscosity of said first polyacrylate component, said second polyacrylate component possessing copolymerized photoinitiator functional groups crosslinkable by ultraviolet irradiation, and said second polyacrylate component being selected from the group consisting of polyacrylates, polyacrylate copolymers, polyacrylate mixtures, and mixtures of polyacrylates and polyacrylate copolymers.
