聚碳酸酯/聚对苯二甲酸丁二醇酯（PC/PBT）混合物
聚碳酸酯和PBT具有相当的拉伸强度和弯曲强度。在聚碳酸酯/聚对苯二甲酸丁二醇酯（PC/PBT）混合物中：
聚碳酸酯组分增加了抗冲击性、耐热性和刚度，而聚对苯二甲酸丁二醇酯组分提供了耐化学性
聚碳酸酯/聚对苯二甲酸丁二醇酯混合物即使在低温下也能保持韧性，并提供更好的耐燃油性和耐候性。聚碳酸酯的存在抑制了混合物中结晶聚对苯二甲酸丁二醇酯的湿敏性
PC共混物的模量高于PC单体
共混少量聚酯可以提高PC的弯曲模量
PC的冲击强度更高，这一性能显著提高，因为所有富含聚酯的共混物
PC/PBT共混物与其他PC/聚酯共混物相比，相容性较差

Polycarbonate/Polybutylene Terephthalate (PC/PBT) Blend
Polycarbonate and PBT have comparable tensile strength and flexural strength. In polycarbonate/polybutylene terephthalate (PC/PBT) blend:
The polycarbonate component adds resistance to impact, heat and stiffness, whereas
The polybutylene terephthalate component provides chemical resistance
Polycarbonate/polybutylene terephthalate blendsretain their toughness even at low temperatures and offer improved resistance to fuel and weather. The presence of polycarbonate suppresses the moisture sensitivity of crystalline polybutylene terephthalate in the blend.
PC blends show higher modulus than that of PC alone.
Blending small quantity of polyester can improve flexural modulus of PC
Impact strength of PC being higher, this property improves considerably for all polyester rich blends
PC/PBT blends have poor miscibility as compared to other PC/polyester blends.
