Ok. I give up.  I'm trying to figure out if most injection plastic model kits are made from styrene or polystyrene.  I've seen them used interchangeably, so I'm not sure.

Anyone know?
Thanks!

They may be different chemically, not sure. But I suspect that when someone says 'styrene' they are just shortening the word 'polystyrene', which is the plastic used in most models.

Styrene is the precursor to polystyrene and several copolymers. [1]

Styrene is a liquid that can be chemically linked to create polystyrene, which is a solid plastic that displays different properties. [2]

More than half of the styrene produced is made into polystyrene, a light, stiff plastic widely used in injection-molded or foamed articles. [3]

Nicely annotated Womby.  You may have opened a can of worms with them as I LUUURRRRRVE that sort of sh1t.

Plastic models are primarily moulded from High Impact Polystyrene, referred to in
the industry as HIPS, which is produced by adding polybutadeine to the polystyrene
which improves the mechanical properties by reducing brittleness and adding a small
amount of flexibility.

In their basic or natural form Polystyrene is clear, HIPS is translucent white.

Acrylonitrile butadiene styrene ABS is also widely used in injection-moulding, some model
kits (Pegasus movie rocket kits amongst others) and, a huge variety of toys, are moulded from
ABS.
