Methyl methacrylate is a colorless liquid that is an organic compound. It may also be called MMA. There are several methods of making this compound which can be explained easily since it’s in high demand. It is a monomer that is used for a variety of purposes, including the production of PMMA or polymethyl methacrylate which accounts for the largest use of this chemical compound. In addition, this can be used in the production of creating a PVC modifier as well as a cement that is used as a grout by orthopedic surgeons when doing knee or hip replacements. This cement is typically offered to people that are elderly as it will only last for about 20 years before it needs to be replaced through revision surgery. Some exotic veterinarians also use this cement when it comes to fractures in smaller species of exotic animals for interior repairs to the bone.
