Title:

HEAT-EXPANDING MICROCAPSULE AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2003/099955

Kind Code:

A1

Abstract:

An outer shell comprised of a polymer from a mixture of a nitrile monomer (I), a monomer having, per molecule, one unsaturated double bond and carboxyl (II) and a monomer having, per molecule, two or more polymerizable double bonds (III), optionally together with a monomer copolymerizable with these monomers (IV); and a heat-expanding microcapsule comprising such an outer shell and, enclosed therein, a blowing agent. There are obtained foam particles which, after heat expansion, exhibit a volume retention of 50% or greater under a load of 15 MPa.
