Al~tract--The rate of anionic polymerization of bulk propylene oxide catalysed by potassium alkoxide in the presence of 18-crown-6 ether was followed dilatometrically. Rate constants were obtained at 40, 50 and 60 ° over a range of crown ether concentrations, so allowing calculation of activation en

Diblock-copoly(oxypropylene/oxyethylene)s with moderately-long P-blocks (about 200 P units) and narrow block-length distributions were prepared by use of 18-crown-6 ether and the potassium salt of methoxypropanol in the sequential anionic polymerization of bulk propylene oxide at room temperature an
## Abstract Anionic living polystyrene and polyisoprene were allowed to react with six __tert__‐butyl‐dimethylsilyl ethers of ω‐halo‐1‐alkanols 1–6, the trimethylsilyl ether of bromohydrin (7), the __tert__‐butyldimethylsilyl ether of 4‐bromophenol (8), and __tert__‐butyldimethylsilyl 3‐chloropropy
