ACYLPHOSPHINE OXIDE PHOTOINITIATORS IN METHACRYLATE CASTING RESINS
摘要
A photopolymerisation process for the production of mouldings from methacrylate casting resins wherein 1) a methacrylate casting resin formulation containing (A1) > 50 % methyl methacrylate and/or a prepolymerisate containing a high proportion of methyl methacrylate, (A2) 0 to 40 % other monomers than can be copolymerised with methyl methacrylate, (B) 0.1 to 10 % at least one mono- or bis-acylphosphine oxide photoinitiator, C) 0 to 10 % other photoinitiators, D) 0 to 5 % thermal initiators and E) optionally further customary additives is cast in a mould and 2) is fully cured by irradiation with a light source in the range of from 200 to 800 nm to form a mechanically stable moulding.
