Abstract
A novel methacrylic copolymer contains units derived from at least one alkyl methacrylate and methacrylamide. The units derived from methacrylamide are present in at least 34 wt.-%, based on the total weight of the methacrylic copolymer. A method can be used for preparing these novel methacylic copolymers. Pharmaceutical compositions, nutraceutical compositions, coated pharmaceutical or nutraceutical dosage forms, as well as nano- or microparticles can contain the methacrylic copolymer. The methacrylic copolymer can be used as a coating, as a carrier, and as a matrix for an amorphous solid dispersion.
