摘要：
The biodegradability of polyglycol-based block copolymers is improved by including in the copolymer a lactone. Representative of these biodegradable enhanced copolymers are those made of 1,2-butylene oxide and .epsilon.-caprolactone capped with a homopolymer block of ethylene oxide. The copolymers of this invention have many uses, such as nonionic surfactants, foam control agents, lubricants, and the like.
