The same material can be . As a result, PMMA is a tough and rigid plastic. In addition, it has almost . Poly(methyl methacrylate), which lazy scientists call PMMA , is a clear plastic, used as a shatterproof replacement for glass. When it comes to making windows, PMMA has another advantage over glass.
As you can see from the picture below, the structure of methyl methacrylate kind of looks like Massachusetts. B) Syndiotactic structure , with uniform alternating substituents along the molecular chain. Pendent groups form when a cluster of atoms bonds off of the backbone of the polymer chain.
First the polymer molecules are so big that we can not make the molecular structure or its diagram on a paper. So, their monomers are written with a subscript (n) which denotes no of units that are joined to form the polymeric molecule. It is expected that the PMMA shell on the surface of nano-Sb2O may enhance the dispersion of nano-Sb2Oin PVC and improve the interfacial bonding . Ab initio molecular orbital (MO) calculations were carried out on the anion radical of methyl isobutyrate, a model of the poly(methylmethacrylate) ( PMMA ) anion. Continue reading
