  • Process for producing heat-expandable microspheres and application thereof
    Patent number: 10731021
    Abstract: A process for producing heat-expandable microspheres which enables constant and high-yield production of heat-expandable microspheres having a mean particle size ranging from 0.01 to 10 ?m without deteriorating their expansion performance, and the application thereof. The process produces heat-expandable microspheres containing a thermoplastic resin shell and the blowing agent encapsulated therein. The process includes a step of dispersing a polymerizable component and the blowing agent in an aqueous dispersion medium containing a polyester amide having an acid value (mgKOH/g) ranging from 95 to 140 and a step of polymerizing the polymerizable component.
    Type: Grant
    Filed: June 21, 2016
    Date of Patent: August 4, 2020
    Assignee: MATSUMOTO YUSHI-SEIYAKU CO., LTD.
