摘要

The ultrasonic degradation of poly(ethylene oxide) and poly(vinyl acetate) in benzene solution

and grafting reaction of poly(vinyl acetate) with poly(ethylene oxide) were studied. It is found that the chain-scission reactions follow the course suggested by D. W. Ovenall. The structure of the copolymer was identified by IR

NMR and DTA

showing that the copolymer prepared is a graft copolymer mainly. The copolymer formed by irradiating 1% PEO/PVAc solution (PEO/PVAc:1/1 by weight) for a period of 10 min at 18.2 kHz with 2.0 A input current on reversed main circuit

amounts to 10.5%.
