    摘要： This invention is concerned with polymerizable compositions, a process for producing and polymerizing such compositions and the resultant polymerization product. Compositions comprising the reaction product of polycarbodiimides and .alpha.,.beta.-unsaturated carboxylic acids are dissolved in vinyl monomers and subject to free-radical polymerization. The polymerization product may contain up to about 300 weight percent of conventional fillers.

    摘要： A continuous process for the production of microcapsules having polymeric walls and a solid or liquid core which comprises mixing a polyisocyanate with the material to be encapsulated, reacting the resulting mixture, a polyamine, and an aqueous phase containing a dispersion aid, the reaction being initiated in a high-turbulence mixing zone to form an emulsion, and subsequently transferring the reaction product to a multiple-stage cascade of vessels, the temperature being increased from stage to stage and being kept constant during each stage.
