Perhaps you should try some spelling variations:
poli » poly, poll, pol
pool » poor
pole » pope, pose, poly
polyolefin » polyolefins
pollmann » kollmann, gollmann, wollmann
dooleys » dooley, doleys, dodsleys

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: ((((poli OR pool) OR pole) OR (polyolefin OR post)) OR (pollmann OR dooleys)).
• Adding a wildcard symbol may retrieve word variants: ((((poli or pool) or pole) or (polyolefin or post)) or (pollmann or dooleys))*.
