Abstract
An adhesive composition comprised of (A) a latex of a self-crosslinking, carboxyl group-containing highly saturated nitrile-conjugated diene copolymer rubber containing 0.3-10 wt. % of self-crosslinking monomer units, and (B) a resorcinol-formaldehyde resin. A composite comprised of a fibrous material, which has been treated with the adhesive composition, and a nitrile group-containing highly saturated copolymer rubber. This composite is useful for belts.
Claims7
An adhesive composition comprising:
- A) a latex of a self-crosslinking, carboxyl group containing a nitrile-conjugated diene copolymer rubber having an iodine value not larger than 120 and containing at least 0.02 equivalent weight, per 100 parts by weight of the copolymer rubber, of a carboxyl group;
- said latex having a pH value not larger than 9.0, and said copolymer rubber being a hydrogenated product of a copolymer comprised, based on the weight of the copolymer of:
- a) 30 to 80% by weight of conjugated diene monomer units,
- b) 10 to 60% by weight of .alpha., .beta.-unsaturated nitrile monomer units,
- c) 0.3 to 10% by weight of an ethylenically unsaturated self-crosslinking monomer units,
- d) 1 to 10% by weight of ethyleneically unsaturated carboxylic acid monomer units, and
- e) 0 to 50% by weight of at least one copolymerizable other ethylenically unsaturated monomer units, and
- B) 5 to 30 parts by weight, based on 100 parts by weight of said copolymer rubber latex, of a resorcinol-formaldehyde resin.
