Polymer-supported novel optically active crown ethers were prepared by the reaction of chiral crown ethers derived from L-(+)-tartar& acid and 4-chloromethylated polystyrene resins crosslinked with 2 mol% of divinylbenzene. The ring substitution which indicates percentages of fnnctionalized unit of

## Abstract Active one‐phase Ti‐based supported catalysts were prepared by interacting the activated silica gel (0.8 mmol OH groups/g) with R~x~AlCl~3–x~ (__x__ = 1–3, Al/OH = 0.9–1.0), then with TiCl~4~ and R~2~Mg (Mg/Ti = 1–16), and finally with R~3~Al (Al/Ti = 0–16). The catalyst activity in the
