摘要: Racemic and optically active protected glycidols (as 1-ethoxyethyl ethers) are readily polymerized with anionic initiators (e.g., CsOH). Polymers molecular weights up to 30 000 obtained without cleavage of the protective group. Oligomers (degree polymerization [DPn] 5 10) prepared using an aluminium complex derived from a Schiff's base. The thioglycidol (synthesized glycidol) leads very high-molecular-weight polymers (150 000–320 000) or coordinated initiators. Copolymers glycidol ethylene oxide KOH as initiator. Regeneration hydroxyl groups in is carried out acidic cleavage. Treatment polyglycidol formic acid first formate polyglycidol. Then, after saponification, pure obtained. use aqueous hydrochloric directly free polymer.
