Ricinoleic acid (also) polymer rubber constituent, ricinoleic acid (also) polymer rubber building a bridge body and its application

摘要

PPROBLEM TO BE SOLVED: To provide a ricinoleic acid (co)polymer rubber composition environmentally friendly and having excellent moldability and a crosslinked rubber having excellent flexibility and mechanical characteristics while keeping the low-temperature characteristics suitable for rubber uses compared with conventional ricinoleic acid (co)polymer rubber composition. PSOLUTION: The ricinoleic acid (co)polymer rubber composition includes (A) 100 pts.wt. of a ricinoleic acid (co)polymer having a specific weight-average molecular weight, (B) 10-200 pts.wt. of a reinforcing agent and (C) 0.01-5 pts.wt. of a sulfur compound.
