Abstract
(Meth)acrylic/glutarimide copolymers, well suited, e.g., for optical applications, having enhanced glass transition temperatures (Tg), are prepared by salifying the acid functions of (meth)acrylic ester/(meth)acrylic acid copolymers, and then imidifying such "intermediate" salified copolymers into the subject (meth)acrylic/glutarimide polymers.
