Polymer Properties Question

  1. Nov 8, 2009 #1
    Tell me what your ideas are for this multiple choice question

    Compared to semiconductors, metals, and ceramics, polymers:

    a) have lower melting points
    b) tend to have lower densities
    c) deform plastically to a higher extent
    d) have lower electrical conductivity
    e) all of the above
    f) a, b, & c
    g) a, b, & d

    As of now I'm 99% sure that a is true, polymer tend to melt easily. I'm actually sure that b is true also.

    do polymers (I'm assuming things like plastics, but there are also natural and biopolymers) conduct electricity? What about metals, ceramics and semiconductors?

    What does plastic deformation invlove? Which property of a material determines its plastic deformation?
