PROPYLENE POLYMERISATION PROCESS IN THE PRESENCE OF AN ANTI-FOULING AGENT

摘要

A propylene polymerisation process carried out in the presence of an anti-fouling agent; characterised in that the anti-fouling agent comprises an anti-fouling polymer containing (a) one or more blocks -(CH-CH-O)- where each k is in the range from 1 to 50; and (b)one or more blocks -(CH-CH(R)-O)- where R comprises an alkyl group having from 1 to 6 carbon atoms and each n is in the range from 1 to 50; and terminated by a R' and a R" end groups wherein R' is OH or an alkoxy having from 1 to 6 carbon atoms and R" is H or an alkyl having from 1 to 6 carbon atoms, and the anti-fouling polymer is solvated in a solvent comprising cyclohexane when added to the polymerisation medium.
