Abstract
A polymeric molding composition from water soluble compounds admixed from a two part wet phase and dry phase combination comprised from the interaction by nucleophilic substitution of an hydroxyl group of an alcohol, having more than one functional hydroxyl group, by a polymeric compound or by a polymeric hydroxyl compound hydrolyzed in a water solution wherein each monomer has an alkyl hydroxyl group, an hydroxyl group or other functional group capable of forming an alkoxide by means of the action of an alkaline earth metal salt electrolytic initiator to provide a self sustaining ionic reaction to create a fast forming polymeric composition which has an initial quick set time to form a flowable gel-like mass and which has a delayed set time to form a rigid non-sticky durable product. The dry phase includes a water solubilizing powder capable of forming a gel and the electrolytic initiator. The wet phase includes water as the solubilizing medium and a water soluble gel modifying substance.
