    Abstract: A process for producing thermo-expansive microcapsules wherein a polymerizing mixture containing ethylenic unsaturated monomer and a blowing agent is suspend-polymerized to microencapsulate the blowing agent with the resultant polymer. The above-mentioned suspension-polymerization is performed with the presence of at least one compound selected from the group consisting of polypeptides and derivatives thereof as a suspension stabilizer. The process can control the particle size of microcapsules easily, attain stable reaction system and produce thermo-expansive microcapsules that disperse well in medium such as paint or inks.
