- Jun 10 5:26 PMFor what it's worth:
Encyclopedia Britannica describes photopolymer as a "plastic precursor" which "polymerizes to an insoluble plastic when exposed to light."
And dictionary.com defines photopolymer as "a polymer or plastic that undergoes a change in physical or chemical properties when exposed to light."
Not that I suppose that really proves anything. But I do know if you hand a photopolymer plate to any 10 year old and ask them what it's made of they will tell you "plastic." So sue me (LOL).

>Maybe it was the famous reference to "plastics" in the movie The Graduate that has us all brainwashed,but as an FYI footnote to Gerald's previous comment, note that some polymers are plastics, but certainly not all.
