Engineering Material Polymers Pptx Polymerization reactions are either addition polymerization, involving chain growth, or condensation polymerization, involving step growth. polymers have a variety of applications and properties depending on their structure and bonding forces. download as a pptx, pdf or view online for free. Issues to address • what are the general structural and chemical characteristics of polymer molecules? • what are some of the common polymeric materials, and how do they differ chemically? • how is the crystalline state in polymers different from that in metals and ceramics ? chapter 14:polymer structures what is a polymer?.
Engineering Material Polymers Pptx Elastomers elastomermaterials are those materials that are made of polymers that are joined by chemical bonds, acquiring a final slightly crosslinked structure. natural rubber material used in the manufacture of gaskets, shoe heels. Phenolic resins combine the high reactivity of phenol and formaldehyde to form polymers and oligomers called resoles and novolacs. these materials are combined with fibrous fillers to give a phenolic resin, which when heated provides rapid, complete cross linking into highly cured structures. There are two basic types of synthetic polymers. thermoplastics (plastics, styrofoam) these can be softened by heating and hardened by cooling easily recycled. Polymerization the use of heat, pressure or a chemical catalyst to link monomer material into polymer chains.
