Title:
RATTLE NOISE REDUCTION MATERIAL AND THERMOPLASTIC RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/116569
Kind Code:
A1
Abstract:
Provided is a rattle noise reduction material comprising a (meth)acrylic ester-based polymer (B) which has: a polymer (b1) that includes a structural unit derived from an acrylic ester compound and a structural unit derived from a methacrylic ester compound and that has a glass transition temperature of -15°C to +5°C; and a polymer (b2) that includes one or more structural units selected from the group consisting of structural units derived from methacrylic ester compounds, structural units derived from aromatic vinyl compounds, and structural units derived from vinyl cyanide compounds, in which the temperature (peak temperature) at which a peak value of primary dispersion of tanδ measured on the polymer (b1) is shown is -5°C to +20°C, and in which the peak intensity that is the peak value is not less than 2.055.
