Abstract: A degradable plug for use in a wellbore, wherein the degradable plug involves an inducibly degradable composition containing solid polyacetal. After placing the degradable plug in a wellbore, it can be degraded by allowing a portion of the polyacetal present in the inducibly degradable composition to react with an inducer.
