Since Francois mentioned 3M, that reminded me they make lots of 
*plastic* optical films that are used in your mobile phone to improve 
brightness, viewing angle and sunlight readability. Another area that 
has been continuously improving over the last decade and will continue 
to, but which most consumers wouldn't know about.

Or surely you've heard about 3D printers recently? The materials they 
use (the professional ones, not the hobby ones) are state-of-the-art 
polymers to give the final piece properties as close as possible to 
traditional injection moulded plastics. It's not like those materials 
existed 30 years ago.
