Patent number: 12110385Abstract: 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.Type: GrantFiled: March 27, 2020Date of Patent: October 8, 2024Assignees: SEKISUI CHEMICAL CO., LTD., TOKUYAMA SEKISUI CO., LTD.Inventors: Kenichi Matsumura, Norikazu Mashino, Kento Murakami, Nami Nakajima, Yasunari Kusaka, Takehisa Sugaya, Masahiko Yamagata

Patent number: 12104051Abstract: 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.Type: GrantFiled: March 27, 2020Date of Patent: October 1, 2024Assignees: SEKISUI CHEMICAL CO., LTD., TOKUYAMA SEKISUI CO., LTD.Inventors: Kenichi Matsumura, Norikazu Mashino, Kento Murakami, Nami Nakajima, Yasunari Kusaka, Takehisa Sugaya, Masahiko Yamagata
