Perhaps you should try some spelling variations:
polyene » polyenes, polyeder, polyenne, polyane, polypne, poolyene, polyyene, poleyene
polye » polyen, polya, polyp, poolye, polyye, poleye
polyeylen » polyenylen, polyaylen, polypylen, poolyeylen, polyyeylen, poleyeylen, polyethylen, polyetylene, polyenen
pol » pool, poly, pole
polyole » poolyole, polyyole, poleyole, polyols, polyol
woolle » woollen, woolley, woollet
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: ((((polyene OR polye) OR (pol OR woolle)) OR ((polyole OR polyeylen) OR post)) OR poolya).
• Adding a wildcard symbol may retrieve word variants: ((((polyene or polye) or (pol or woolle)) or ((polyole or polyeylen) or post)) or poolya)*.
