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 8.0% or more and 30.0% or less, 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. ## Claims ### Claim 1 A chlorinated polyvinyl chloride resin, comprising 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 8.0% or more and 50.0% or less, 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, wherein the chlorinated polyvinyl chloride resin has a degree of polymerization of 100 to 2,000, and wherein the chlorinated polyvinyl chloride resin contains units (a) to (c) represented by the following formulas (a) to (c), and a proportion of the structural unit (a) is 5.0 mol % or higher and 90.0 mol % or lower, a proportion of the structural unit (b) is 5.0 mol % or higher and 40.0 mol % or lower, and a proportion of the structural unit (c) is 5.0 mol % or higher and 55.0 mol % or lower, relative to total number of moles of the structural units (a), (b), and (c) —CH2—CHCl— (a) —CH2—CCl2— (b) —CHCl—CHCl— (c). ### Claim 2 (depends on 1) The chlorinated polyvinyl chloride resin according to claim 1, wherein the chlorinated polyvinyl chloride resin comprises two components including a A100 component and a B100 component, and has a percentage of the B100 component (B100 component/(A100 component+B100 component)) of 9.0% or more and 30.0% or less, and the two components are identified by measuring the chlorinated polyvinyl chloride resin by a solid echo method using pulse NMR at 100° C. to give a free induction decay curve of 1H spin-spin relaxation, and subjecting the free induction decay curve to waveform separation into two curves derived from the A100 component and the B100 component in order of shorter relaxation time using the least square method. ### Claim 3 (depends on 1) The chlorinated polyvinyl chloride resin according to claim 1, having an amount of added chlorine of 1.0 to 16.0% by mass. ### Claim 4 (depends on 1) A resin composition for molding, comprising the chlorinated polyvinyl chloride resin according to claim 1. ### Claim 5 (depends on 4) The resin composition for molding according to claim 4, comprising 1 to 30% by mass of an impact resistance modifier. ### Claim 6 (depends on 4) A molded article molded from the resin composition for molding according to claim 4. ### Claim 7 (depends on 6) The molded article according to claim 6, further comprising a glass fiber or a carbon fiber. ### Claim 8 (depends on 6) The molded article according to claim 6, which is a member for use in transportation machinery. ### Claim 9 (depends on 6) The molded article according to claim 6, which is a member for use in battery systems. ### Claim 10 (depends on 1) The chlorinated polyvinyl chloride resin according to claim 1, wherein the chlorinated polyvinyl chloride resin has an amount of added chlorine of 3.2 to 12.2% by mass, and the proportion of the structural unit (a) is 21.5 mol % or higher and 72.6 mol % or lower, the proportion of the structural unit (b) is 10.7 mol % or higher and 31.3 mol % or lower, and the proportion of the structural unit (c) is 16.7 mol % or higher and 55.0 mol % or lower.
