TERMOEXPANDERBARA MIKROSFERER |
摘要 |
Microspheres, the blowing agent of which is microencapsulated with a thermoplastics having an acrylonitrile moiety, are prepared. Acrylonitrile monomer remaining therein is eliminated from the microspheres by cyanoethylation. The microspheres have an excellent solvent-resistance and an expansibility hardly changeable with time but no harmfulness attributed to the acrylonitrile monomer. |
