A process for stabilizing polymers is provided comprising:

Method for stabilizing monovinylarene/conjugated diene copolymers and a

Apparatus and methods are provided for simultaneously winding at least two filament reinforced thermoplastic strips onto a mandrel or similar form, comprising: a rotatable mandrel for receiving the strips; a winding assembly for rotating the mandrel and winding the strips onto the mandrel; a strip feeder, for feeding the strips to the mandrel as the mandrel rotates; and a joining assembly, located between the feeder and the mandrel, for ceaselessly urging the strips into generally parallel, contiguous juxtaposition. The joining assembly comprises an arcuate member having an inside radius positioned to deflectingly contact the strips between the strip feeder and the mandrel. Preferably, the joining assembly is connected to the exit of the strip feeder.

Filament winding apparatus and method

A filament winding process is disclosed for producing articles having a layer of wound helically extending fibers sandwiched between generally longitudinal fibers. The process is well adapted for use with thermoplastic resins and for producing articles having a high resistance to bending. In a preferred embodiment, there is disclosed a filament wound baseball bat formed from a thermoplastic resin, (poly(arylene sulfide).
