Title:
FIBER-REINFORCED VULCANIZED RUBBER COMPOSITION AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/188104
Kind Code:
A1
Abstract:
The present invention prepares a rubber composition by using a rubber ingredient (A) in combination with modified cellulose nanofibers (B) including, bonded thereto, a fluorene compound (B1) having aryl groups at the 9,9-position. The fluorene compound (B1) may be a compound represented by formula (1). (In formula (1), rings Z each represent an arene ring, R1 and R2 each represent a substituent, X1 represents a heteroatom-containing functional group, k is an integer of 0-4, n is an integer of 1 or larger, and p is an integer of 0 or larger.) This rubber composition is excellent in terms of mechanical properties including strength, elongation, and hardness.
