Abstract
Mercaptoalkanoic acids and thiodialkanoic acids are reacted with a poly(oxyalkylene)-polyol to form poly(oxyalkylene)-polyester-poly(monosulfide)-polythiols which are useful as encapsulating materials and mold compositions when oxidatively coupled or cured. In one embodiment, a polymeric reaction product, either in the uncured state or partially cured state, is used for the preparation of flexible molds from which regularly or irregularly shaped objects can be made.
