Perhaps you should try some spelling variations:
polyyen » polyen, polyynes, polyaeno, poolyyen, polyyyen, pollyyen
pole » pope, pose, poly, poole, polye, polle
pol » pool, poly, poll
polyylen » poolyylen, polyyylen, pollyylen, polyolen, polyblend, polyynes
woolle » woollen, woolley, woollet
poolyolen » polyolen, polyole
poolya » pooya, pooly, poorya

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((polyyen OR pole) OR (pol OR woolle)) OR ((poolyolen OR polyylen) OR post)) OR poolya).
• Adding a wildcard symbol may retrieve word variants: ((((polyyen or pole) or (pol or woolle)) or ((poolyolen or polyylen) or post)) or poolya)*.
