ABSTRACT:
Polyetherimide resins which crystallize from the melt contain crystallizing repeating units based on biphenoldianhydride or hydroquinone dianhydride and a linear aromatic diamine. The melt crystalline polyetherimides exhibit improved solvent resistance. The melt crystalline polymers retain the advantageous properties associated with their known amorphous polyetherimide counterparts.
