Abstract
A method for the bonding of amorphous thermoplastic materials such as polyarylene sulfides, comprising suitably surface treating these materials, and using one or more or a combination of the following bonding agents: a suitable solvent such as N-methylpyrrolidone, a solution of the thermoplastic material in a suitable solvent; or a film of the thermoplastic material pretreated with a suitable solvent. Clamping of the treated surfaces followed by heating at a suitable pressure and temperature for a period of time sufficient to evaporate the bonding solvent, facilitates the bonding process.
