Title
(EN) NITRILE COPOLYMER LATEX COMPOSITION AND NITRILE COPOLYMER RUBBER COMPOSITION
(JA) ニトリル共重合体ラテックス組成物およびニトリル共重合体ゴム組成物
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a rubber composition giving a nitrile copolymer rubber crosslinked material having low gasoline permeability and excellent sour gasoline resistance and cold resistance, and to provide a latex composition giving the rubber composition.

SOLUTION: The nitrile copolymer latex composition comprises latex of nitrile copolymer rubber (A), which includes 10-75 wt% of ,-ethylenically unsaturated nitrile monomer unit, 5-89.9 wt% of conjugated diene unit, and 0.1-20 wt% of a cationic monomer unit and/or a monomer unit forming a cation, an inorganic filler (B) having an aspect ratio of 30-2,000, and a coupling agent (C). The content of the coupling agent (C) is 0.1-20 pts.wt. based on 100 pts.wt. of the nitrile copolymer rubber (A).
