The present invention relates to a high-strength inflammable blend resin composition including a polyphenylene sulfide resin and a polyethylene terephthalate resin. More specifically, the resin composition of the present invention includes: a basic blend resin containing 10 to 80 wt. % of a polyphenylene sulfide resin, and 20 to 90 wt. % of a polyethylene terephthalate resin; and 0.1 to 20 parts by weight of a modified polystyrene or a styrene-based elastomer with respect to 100 parts by weight of the basic blend resin.

The present invention relates to a method of prepairing a heat-resistant polyamide by carrying out condensation polymerization with a monomer mixture including a diester compound and a diamine compound. The present invention provides an economical method of prepairing a heat-resistant polyamide in that a monomer, a raw material, is simply and chiefly prepared, and the polymerizing reaction time is short because it does not need solvent separately.
