ABSTRACT:
A silane-containing methacrylate resin composition which produces non-yellowing polymers. The composition contains 20-99.9% by weight (meth)acrylic acid ester, optionally other comonomers or polymers and softeners as well as 0.1-30% by weight of a silane. 100 parts by weight of this mixture are polymerized in the presence of a free radical initiator, Cu.sup.2+ and a quaternary amine. The components can be stored in premixtures and brought to reaction. The polymer can be used in glass laminates.
