Polymerization with Cr-oxide/SiO2 catalyst gives initially low activity, then a gradual increase in activity. Several factors are discussed that might be responsible for the long time to reach full activity: Chemical, transport restrictions, catalyst fracturing. A locking and unlocking of Cr-C bond cycle is proposed. A concequence of this theory is that as soon as the pores in the catalyst have been filled with polymer, polymerization must virtually stop. Slowly, however, pressure in the pores build up and fractures the catalyst, making an increase in polymerization rate possible.
