1. The time has probably come to adapt a new name more worthy of the
exciting
range
of
polymer
materials
with
many
different
properties
which
are available to engineers.

2.It should be noticed that compression moulding would be impracticable
for thermoplastics which have no curing stage during which a chemical
reaction take place; because the mould would require cooling each cycle
in order to allow the component to harden sufficiently for extraction.

3.To
sum
up
there
is
a
complex
time-
temperature-stress-strain
relationship which affects the mechanical behavior of all plastics, and
