  • Patent number: 12110385
    Abstract: The present invention provides a chlorinated polyvinyl chloride resin that not only has high heat resistance and high mechanical strength but also is excellent in molding processability and is very easy to soften and additionally enables production of a molded article with high gloss. 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.

  • Patent number: 12104051
    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.

  • Patent number: 10428724
    Abstract: A cooling device for an internal combustion engine includes a circulation path, a coolant temperature sensor, a coolant pump, and an electronic control unit. The electronic control unit is configured to execute processing for performing feedback control on power of the coolant pump such that the output of the coolant temperature sensor becomes a target temperature, micelle determination processing for determining whether or not micelles are added to a coolant based on pump work of the coolant pump and the flow rate of the coolant flowing through the circulation path, Toms determination processing for determining whether or not the flow rate of the coolant satisfies a Toms effect expression condition, and correction processing for increasing a relative value of the output of the coolant temperature sensor with respect to the target temperature when the micelles is added and the Toms effect expression condition is established.
