## Abstract **Summary:** In this paper, a mathematical model describing olefin polymerization with metallocene catalysts is presented. It is an improvement of a previous model, the “particle growth model” (PGM) proposed by, among others, one of the authors of the present work and derives from the s
Polymer-supported cryptands were prepared by the reaction of hydroxyl-containing cryptands and chloromethylated polystyrene resin. The polymer-supported cryptands were effective catalysts for aqueous organic two-phase reactions.
## Abstract Four supported metallocene catalysts were synthesized directly on silica [Si(CpZrCp), Si(CpZrInd), Si(IndZrCp), and Si(IndZrInd)]. The first ligand was chemically tethered to silica (internal ligand) while the second was free from silica (external ligand). The polymerization of ethylene
