Abstract
A method of making a thermoplastic composition comprises melt extruding a poly(arylene ether) powder to form a first pelletized poly(arylene ether); and melt extruding the first pelletized poly(arylene ether) to form a second pelletized poly(arylene ether), wherein the second pelletized poly(arylene ether) has a level of butyraldehyde less than the first pelletized poly(arylene ether) and the second pelletized poly(arylene ether) has a level of trimethylanisole less than the first pelletized poly(arylene ether).
Claims9
A method of making a thermoplastic composition comprising melt extruding a poly(arylene ether) powder to form a first pelletized poly(arylene ether);
- and melt extruding the first pelletized poly(arylene ether) to form a second pelletized poly(arylene ether), wherein the second pelletized poly(arylene ether) has a level of butyraldehyde less than the first pelletized poly(arylene ether) and the second pelletized poly(arylene ether) has a level of trimethylanisole less than the first pelletized poly(arylene ether).
A thermoplastic composition produced by a method comprising melt extruding a poly(arylene ether) powder to form a first pelletized poly(arylene ether);
- and melt extruding the first pelletized poly(arylene ether) to form a second pelletized poly(arylene ether), wherein the second pelletized poly(arylene ether) has a level of butyraldehyde less than the first pelletized poly(arylene ether) and the second pelletized poly(arylene ether) has a level of trimethylanisole less than the first pelletized poly(arylene ether).
