  The present invention provides a biodegradable recycled polyester resin and a production process therefor, wherein the polyester resin is inexpensive and economical due to use of recycled aromatic polyesters, and further, can solve problems of wastes by affording biodegradability to the aromatic polyester which has so far been assumed to have no biodegradability. The biodegradable recycled polyester resin, according to the present invention, is obtained by a process including the step of carrying out a reaction of a recycled aromatic polyester (A) with an aliphatic polyester (B) having a number-average molecular weight of 3,000 to 300,000 in a reaction ratio (weight ratio) of (A)/(B) = 95/5 to 5/95, thereby affording biodegradability to the recycled aromatic polyester (A).

  本发明提供了一种可生物降解的再生聚酯树脂及其生产工艺，其中，由于使用了再生芳香族聚酯，该聚酯树脂价格低廉且经济实惠，此外，由于芳香族聚酯迄今为止一直被认为不具有生物降解性，本发明可通过赋予芳香族聚酯生物降解性来解决废物问题。根据本发明，可生物降解的再生聚酯树脂是通过以下工艺获得的：将再生芳香族聚酯（A）与具有 3,000 至 300,000 数均分子量的脂肪族聚酯（B）按（A）/（B）=95/5 至 5/95 的反应比（重量比）进行反应，从而使再生芳香族聚酯（A）具有生物降解性。
