A~traet--Reactivity ratios have been determined for the anionic copolymerization of ethylene oxide and butylene oxide in bulk at temperatures of 40 and 60 °. The ratios were obtained from the variation with feed composition of: (i) copolymer composition; and (ii) triad sequence probabilities. Finite
Reactivity ratios have been determined for the anionic copolymerization of ethylene oxide and propylene oxide in bulk over the temperature range 0-80°C. The ratios were obtained by two methods, the first using the variation of copolymer composition with monomer feed composition according to the May~
## Abstract We present a facile access route to hydroxy‐functional narrow disperse microspheres of well‐defined grafting density (GD). Ethylene oxide has been grafted from highly crosslinked poly(divinyl benzene) microspheres by anionic ring‐opening polymerization using __sec__‐butyllithium as acti
