METHOD OF POLYMERISING POLYMERS IN GASEOUS PHASE |
摘要 |
A process for the gas-phase polymerization of polymers which allows for the introduction of an unsupported polymerization catalyst system into the gas-phase reactor, wherein the unsupported polymerization catalyst system comprises (i) a non-volatile materials fraction containing a polymerization catalyst; (ii) a solvent fraction which is at least partially miscible with the non-volatile materials fraction and which is sufficiently volatile to allow for the formation of polymerization catalyst particles when the mixture of the solvent fraction and the non-volatile materials fraction is sprayed into the reactor; (iii) a compressed fluid; and (iv) optionally a slowly vaporizing solvent. |
