Which of the monomers (A-E) listed above gives a densely cross-linked network when
polymerized under the appropriate conditions?
Which of the above monomers is polymerized free radically at high pr...
Lecture 4, PE + PP
Generally decreases with increasing degree of
crystallinity.Semi-crystalline polymers usually appear opaque
because of the difference in refractive index of the amorphous

Lectures 11 and 12
Small molecules usually cannot penetrate or diffuse through
the crystalline domains, hence “barrier properties”, which
make a polymer useful for things like food wrap, increase with
degree of cryst...
