ABSTRACT:
A new type of aromatic polyamide powder including a large number of fine coalescible particles which have an average size of from 0.1 to 10 .mu.m, which include at least one aromatic amide polymer including 40 to 100 molar % of recurring m-phenylene isophthalamide units and 0 to 60 molar % of at least one other type of additional recurring aromatic amide units, for example, m-phenylene terephthalamide units, and which coalesce with each other to form porous agglomerates having an average size of from 10 to 400 .mu.m and a surface area of from 1 to 20 m.sup.2 /g, and can be compression molded, optionally in mixture with a reinforcing additive, for example, aromatic polyamide fibers having a length of 3 mm or less, at a temperature of 200.degree. to 400.degree. C. under a pressure of 300 to 1000 kg/cm.sup.2 for 20 minutes to 5 hours, to produce shaped articles having excellent mechanical properties and appearance.
