    摘要: The present invention provides a process for producing thermo-expansive microcapsules that disperse better than conventional products. In this process, thermo-expansive microcapsules are produced through suspension-polymerization in which a polymer is produced from polymerizing unsaturated ethylene monomers under the existence of one or more of metal compounds selected among zirconium compounds and titanium compounds and the resultant polymer microencapsulates a volatile blowing agent gasifying below the softening point of the polymer.

    摘要: 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.

    摘要: A method that heat-expandable microspheres includes the use of a shell of thermoplastic resin and a non-fluorine blowing agent encapsulated therein having a boiling point not higher than the softening point of the thermoplastic resin. The method includes, a step of dispersing an oily mixture containing a polymerizable component, the blowing agent, and a polymerization initiator containing a peroxydicarbonate in an aqueous dispersing medium to polymerize the polymerizable component contained in the oily mixture. The resultant heat-expandable microsphres have a shell which is less apt to become thinner than its theoretical value, contain minimum amount of resin particle inside their shell, and have excellent heat-expanding performance.
