Its calculation principle is to divide the entire polymer molecular chain into several fragments of similar volume size, which are generally called coarse-grained beads. These microspheres are usually ...

The extended-release beads are prepared using sugar/starch spheres upon which a drug/excipient layer is coated, followed by an ammonio-methacrylate copolymer coating (Figure 2A). After ...

The primary use of methyl methacrylate is the production of acrylic plastics and resins (trade names are Lucite, Plexiglas and Perspex) for sheeting and molding compounds. These are used in ...
