Document Type and Number:
WIPO Patent Application WO/2024/062932
Kind Code:
A1
Abstract:
Provided is a composition for a vibration-damping material capable of yielding a vibration-damping material having a wide temperature range in which the tanδ value is 0.5 or more. Provided is a vibration-damping material obtained by curing this composition for a vibration-damping material, and provided is a member containing this vibration-damping material. This composition for a vibration-damping material specifically contains 0.05-9.5 mass% of a polyfunctional polymerizable compound (A) represented by general formula (a1) and 90.5-99.95 mass% of a polymerizable monomer (B). [In general formula (a1), R1 to R3 each independently represent a hydrogen atom, a C1-6 alkyl group, a C2-6 alkenyl group, a C6-12 aryl group, or a C7-13 aralkyl group, and R4 represents a (meth)acryloyl group, a vinyl phenyl group, or a C2-6 alkenyl group. n represents an integer of 1 to 6.]
