Abstract
PURPOSE: To obtain a non-toxic hydrolyzable polymer, by polymerizing an alkylene carbonate in the presence of a tin alkoxide complex as a catalyst while supperssing the decarboxylation.
CONSTITUTION: (A) An alkylene carbonate of formula I: [R1, R2, R3 and R4 are (halogenated) hydrocarbon groups] is polymerized in the presence of (B) 0.1W 5mol% based on (A) of a tin alkoxide, of formula II or III: (M is alkali metal, M' is alkaline earth metal; R is alkyl group; X is OR, halogen, SR, OOCR, alkyl, SCN, OCN, NCO, or NCS; x is 1 or 2) as a catalyst, preferably at 100W180°C.
EFFECT: Alternating copolymers of a polyalkylene oxide and the alkylene carbonate can be obtained.
