9、her.Polymers that contain the vinyl group are classed as vinyls.Some examples of polymers include Styrofoam,Teflon,Orlon,and Plexiglas(or Lucite).Plexiglas is thermoplastic,meaning it softens and can be shaped when heated but becomes rigid again on cooling.Polymerization-the making of plastics Vinyl

10、13-3.Petroleum Products Table 13.313-10 Polymers.A copolymer is a polymer that consists of two different monomers.Dynel and Saran Wrap are examples.Certain monomers that contain two double bonds in each molecule form flexible,elastic polymers called elastomers;rubber and neoprene are examples.Polyam

11、ides and polyesters are polymers produced by chemical reactions rather than by the polymerization of monomers.13-10 Polymers.Teflon is polymer with a strong bond between carbon and fluorine atoms.It is used as a no-stick surface in cookware.13-11.Carbohydrates D-AlloseD-AltroseD-GlucoseD-MannoseD-Gu
