Perhaps you should try some spelling variations:
polyen » polyenes, poolyen, polyyen, pollyen
polyene » polyenese, polyenes, polyeder, poolyene, polyyene, pollyene
pole » pope, pose, poly, poole, polye, polle
pol » pool, poly, poll
poolyolen » polyolen, polyole
popeylen » popeye, propylen, popeyes
pooya » polya, pooja

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: (((((polyen OR polyene) OR pole) OR (pol OR woollen)) OR ((poolyolen OR popeylen) OR post)) OR pooya).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((((polyen OR polyene) or pole) or (pol or woollen)) or ((poolyolen or popeylen) or post)) or pooya)".
• Adding a wildcard symbol may retrieve word variants: (((((polyen OR polyene) or pole) or (pol or woollen)) or ((poolyolen or popeylen) or post)) or pooya)*.
