Drawable high tensile strength aramids

A process for drawing aramids, comprising,

• heating an aramid selected from the group consisting of:
• aramid A consisting essentially of about 70 to about 95 mole percent of a first unit of the formula ##STR11## and about 30 to about 5 mole percent of a second unit of the formula ##STR12## wherein X.sup.1 and X.sup.2 are independently selected from the group consisting of chlorine, bromine and methyl;
• and
• aranid B consist essentially of about up to 7 mole percent of a first unit of the formula ##STR13## about 30 to about 70 mole percent of a second unit of the formula ##STR14## and about 70 to about 30 mole percent of a third unit of the formula ##STR15## wherein X.sup.1 and X.sup.2 are independently selected from the group consisting of chlorine, bromine and methyl
• to a temperature at which said aramid can be drawn;
• drawing said aramid at said temperature by applying sufficient force to draw said aramid;
• provided that:
• said aramid is drawn at least 1.5%;
• said drawn aramid has an apparent crystallite size of about 35 Angstroms or larger;
• said drawn aramid has an orientation angle of 12.degree. or less;
• said drawn aramid has a tensile strength of about 20 grams per denier or more;
• and
• the tensile strength of said drawn aramid is at least 1.15 times that of said undrawn aramid.
