A stator for a mud motor and methods for manufacturing and using the same, of which one such method includes obtaining a mud motor having a stator made at least partially from a rubber. At least a portion of the rubber is cured by at most about 90%. The method also includes deploying the mud motor into a well as part of a drill string. The rubber is not further cured prior to deploying the mud motor into the well. The method further includes generating torque using the mud motor by pumping a mud through the stator.

A method of preparing a cured thermoplastic material includes curing a thermoplastic polymer having a thermal decomposition temperature greater than or equal to about 200&#xb0; C., at a temperature of about 200&#xb0; C. to about 400&#xb0; C., for a total time of less than or equal to 200 hours. A method of making a shape memory material also includes curing a thermoplastic polymer to prepare a cured thermoplastic material.
