PURPOSE:To obtain a self-bonding resin composition of improved abrasion resistance, by adding a specified amount of fine organic resin powder coated with a fluorocarbon resin to a self-bonding resin composition formed by mixing a phenoxy resin with 2,2'-(1,3-phenylene)bis(2-oxazoline). CONSTITUTION:A phenoxy resin or a mixture (A) thereof with an epoxy resin (e.g., bisphenol epoxy resin) is mixed with 2,2'-(1,3-phenylene)bis(2-oxazoline) or its derivative (B) of a structure as shown in the formula and an organic resin powder (C) surface-coated with a fluorocarbon resin of a mean particle diameter <=20mum (e.g., fine polyethylene or polypropylene powder) in such a ratio that the amount of component C is 0.01-15pts.wt. per 100pts.wt. total of components A and B. This mixture is molten in a solvent (e.g., cyclohexanone) to produce a self-bonding resin composition excellent in hot meltability, heat resistance and abrasion resistance. |
