    Abstract: The present invention provides a chlorinated polyvinyl chloride resin that has resistance to thermal decomposition, provides excellent continuous productivity in molding, and imparts both processability and unevenness-preventing properties to a molded article. The present invention relates to a chlorinated polyvinyl chloride resin, containing three components including a A150 component, a B150 component, and a C150 component, and having a percentage of the C150 component (C150 component/(A150 component+B150 component+C150 component)) of less than 8.0%, the three components being identified by measuring the chlorinated polyvinyl chloride resin by a solid echo method using pulse NMR at 150° C. to give a free induction decay curve of 1H spin-spin relaxation, and subjecting the free induction decay curve to waveform separation into three curves derived from the A150 component, the B150 component, and the C150 component in order of shorter relaxation time using the least square method.

    Abstract: The present invention provides a method for producing a chlorinated polyvinyl chloride which is excellent in thermal stability (initial discoloration resistance, heat-resistant stability) and is capable of providing a transparent article. The present invention relates to a method for producing a chlorinated polyvinyl chloride through thermal chlorination of a reaction solution including a vinyl chloride aqueous suspension that contains a vinyl chloride resin in a hermetically sealable reaction vessel, the method including: step 1 of initiating thermal chlorination by heating the reaction solution to 55° C. to 70° C. and then introducing chlorine into the reaction vessel; step 2 of raising the temperature of the reaction solution while maintaining the temperature inside the reaction vessel not higher than the glass transition temperature of a partially chlorinated polyvinyl chloride; and step 3 of carrying out the thermal chlorination at a predetermined temperature of 85° C. or higher but lower than 115° C. after the chlorine content of the partially chlorinated polyvinyl chloride reaches 58% by weight or more, the steps 1 to 3 being performed under stirring at a net stirring power (Pv) inside the reaction vessel of 0.2 to 2.5 kw/m3 per 1 m3 of the reaction solution.

    Abstract: A thermally expandable multilayer packing for building material, having protruding parts and a body portion in the cross-sectional shape based a plane perpendicular to the longitudinal direction. The thermally expandable multilayer packing includes both a thermally expandable resin composition layer and a thermoplastic resin composition layer, wherein the thermally expandable resin composition forming the thermally expandable resin composition layer contains 100 parts by weight of a resin component containing a chlorinated polyvinyl chloride resin and/or an EPDM, 3 to 300 parts by weight of a thermally expandable graphite, 3 to 200 parts by weight of an inorganic filler and 20 to 200 parts by weight of a plasticizer. The thermally expandable resin composition layer and the thermoplastic resin composition layer are formed by simultaneous co-extrusion using the thermally expandable resin composition and the thermoplastic resin composition.
