## Abstract Poly(ethylene oxide)s having a primary or secondary amino group at one chain end have been synthesized by direct anionic polymerization of ethylene oxide initiated by aminoalcoholates. The ring opening reaction of ethylene oxide by the amino group could be avoided when the alcoholate wa
## Abstract New heterogeneous catalytic systems for anionic ring opening polymerization of oxygenated heterocycles are obtained by grafting alkylaluminium moieties on porous silica. Adding alcohol in excess causes the formation of aluminium alkoxides and allows a rapid exchange reaction between the
