Title:
VINYL CHLORIDE-BASED RESIN FOR PASTE PROCESSING, AND VINYL CHLORIDE-BASED RESIN COMPOSITION FOR PASTE PROCESSING CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP2023138913
Kind Code:
A
Abstract:
To provide a vinyl chloride-based resin for paste processing which suppresses formation of a crater when a sheet is prepared by coating onto a base material, can obtain a foam excellent in surface smoothness in foaming, is also excellent in leakage suppression characteristics from the rear of a coating blade, and is excellent, especially, for wallpaper, and a vinyl chloride-based resin composition for paste processing containing the same.SOLUTION: A vinyl chloride-based resin for paste processing that contains a vinyl chloride-based resin of a large-particle group of a particle diameter of more than 0.5 μm and 5 μm or less, and a vinyl chloride-based resin of a small-particle group of a particle diameter of 0.5 μm or less satisfies (1) an average degree of polymerization of 700-1,000, (2) cumulative weight frequency of the large-particle group of 60-90 wt.% and cumulative weight frequency of the small-particle group of 10-40 wt.% in particle diameter distribution measurement, and (3) a most frequent diameter of the distribution of the large-particle group of 1.55-1.80 μm, and a most frequent diameter of the distribution of the small-particle group of 0.15-0.45 μm.SELECTED DRAWING: None
