Abstract

This invention provides a novel reactive silicon group-containing oxypropylene polymer and a method of producing the same. The reactive silicon group-containing oxypropylene polymer of the invention is an oxypropylene polymer the main polymer chain of which is essentially composed of a repeating unit of the formula (see fig. I) and which has at least one reactive silicon group and at least one urethane bond each terminal to the chain, an Mw/Mn ratio of not more than 1.5 and a number average molecular weight of not less than 3,000. The production method of the invention is characterized by reacting an oxypropylene polymer having an Mw/Mn ratio of not more than 1.5 and a number average molecular weight per terminal functional group of not less than 1,500 with a compound having a reactive silicon group and an isocyanato group.
