Polymer polymerization
WebThe suspension polymerization of ethylene using a highly active Ziegler-Natta catalyst has been investigated. It has been shown that, under appropriate experimental conditons, the monomer transport is hindered neither by pore diffusion inside the suspended particle, nor by film diffusion at the surface of the suspended particle. It was found that there exists an … WebPolymerisation is the process in which many small monomer units combine to form one large polymer molecule. The alkenes ethene and propene are two important feedstocks in …
