Unformatted text preview: [rubber (tires)] Thermosetting polymers- Long chains, linear or branched, that are very strongly cross linked and form a 3d network. Stronger b Thermoplastics- behave in a ductile manner. Long chains. Can be amorphous or crystalline. Can be untangles by applying stress. Upon heating thermoplastics soften and melt. Easily recycled. [PVC (piping)] Increasing temperature in polymers has the following effects:-decrease in elastic modulus-reduction of tensile strength-increase in ductility...
