| titleOfInvention | Method for the preparation of a copolymer of vinyl chloride and an n-substituted maleimide compound |
| abstract | A highly heat-resistant and thermally stable polyvinyl chloride resin can be prepared by copolymerizing vinyl chloride monomer and an N-substituted maleimide compound without decreasing the ingerently excellent properties of polyvinyl chloride resins when the monomer mixture is suspension-copolymerized in an aqueous medium containing a suspending agent which is a combination of three different polymers including: (a) a first partially saponified polyvinyl alcohol having an average degree of polymerization in the range from 700 to 3000 and a degree of saponification in the range from 70 to 95%; (b) a second partially saponified polyvinyl alcohol having an average degree of polymerization in the range from 300 to 600 and a degree of saponification in the range from 35 to 55%; and (c) a water-soluble cellulose derivative of which a 0.2% by weight aqueous solution has a surface tension not exceeding 55 dyn/cm at 25 DEG C., in a specified proportion. |
