Abstract:
1. A thermoplastic composition that comprises: a polyarylene sulfide; glass fibers in an amount of from about 5 wt. % to about 60 wt. % of the composition; a filler that includes a mineral filler, alkoxysilane coupling agent, or a combination thereof; and a nucleating system that comprises boron nitride and an aromatic amide oligomer having the following general formula (I): wherein, ring B is a 6-membered aromatic ring wherein 1 to 3 ring carbon atoms are optionally replaced by nitrogen or oxygen, wherein each nitrogen is optionally oxidized, and wherein ring B may be optionally fused or linked to a 5- or 6-membered aryl, heteroaryl, cycloalkyl, or heterocyclyl; R m is from 0 to 4; X R wherein the weight ratio of aromatic amide oligomers to boron nitride in the composition is from about 1 to about 10, and further wherein boron nitride constitutes from about 0.05 wt. % to about 3 wt. % of the composition, and wherein the composition has a crystallization potential of about 55% or more, as determined by differential scanning calorimetry in accordance with ISO 10350.
