Title:
MIXTURE COMPOSITION OF SYNTHETIC RESIN AND RUBBER
Document Type and Number:
WIPO Patent Application WO/1998/044037
Kind Code:
A1
Abstract:
A mixture composition of a synthetic resin and a rubber, characterized by comprising (A) 90 to 10 % by weight of at least one thermoplastic resin or thermosetting resin and (B) 10 to 90 % by weight of a highly saturated nitrile copolymer rubber which has a Mooney viscosity of 5 to 135 realized by reducing the viscosity by at least 15 points by applying a high shearing force thereto in the presence of an antioxidant, a molecular weight distribution (Mw/Mn) of 3.0 to 5.0, and a Mooney viscosity increase of not larger than 10 points realized by leaving the copolymer rubber to stand at room temperature for 30 days after the reduction of the Mooney viscosity. This composition is so improved in the state of mixing of the synthetic resin with the rubber, that it is improved in various properties.
