HEAT-RESISTANT AND OIL-RESISTANT HOSE

摘要

PURPOSE:To provide a hose comprising a thermoplastic elastomer and excellent in resistances to heat and oil. CONSTITUTION:A heat-resistant and oil-resistant hose has a main component of a thermoplastic graft copolymer which is obtained by allowing an aromatic polyester oligomer having at least 100 deg.C at a flow temperature defined as under to react with a thermoplastic polymer whose main constituent units are a monomer, which has unsaturated double bond having radical reactivity in the same molecules and an epoxy group, and an acrylic ester and whose glass transition temperature is at most 10 deg.C. The flow temperature is a temperature indicating 48000 poises of an apparent melt viscosity measured by a method wherein the aromatic polyester oligomer is melted by heating at a temperature rise rate of 4 deg.C/min and extruded from a nozzle with an inside diameter of 1mm and a length of 10mm under a load of 100kg/cm<2>.
