Perhaps you should try some spelling variations:
polyylei » polyynes, polyyne, polyle, poolyylei, polyyylei, poleyylei
pol » pool, poly, pole
polled » poolled, polyled, poleled, pollen, polluted
poleylen » pooleylen, polyeylen, poleeylen, polecen, polelle
polyes » poolyes, polyyes, poleyes, polyen, polyenes, polydyes
poolyole » polyole, polyols, polyol
roles » role, rules

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: ((((polyylei OR pope) OR (pol OR polled)) OR ((poolyole OR poleylen) OR post)) OR (polyes OR roles)).
• Adding a wildcard symbol may retrieve word variants: ((((polyylei or pope) or (pol or polled)) or ((poolyole or poleylen) or post)) or (polyes or roles))*.
