| Abstract | A novel aliphatic–aromatic polyamide poly(diethylenetriamine terephthalamide) (PDTA) was synthesized by using terephthaloyl chloride (TPC) and diethylenetriamine (DETA). A ammonium polyphosphate (APP)/PDTA mixture was prepared for use as an intumescent flame retardant (IFR) for acrylonitrile–butadiene–styrene terpolymer (ABS). The structure of PDTA was characterized by Fourier transform infrared spectroscopy (FTIR) and $^{1}$H NMR. The thermal properties and thermal decomposition model were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TG). The flame-retardant effect, thermal degradation behavior, and mechanism of IFR–ABS were investigated by limiting oxygen index (LOI), vertical burning test (UL-94), microscale combustion calorimetry test (MCC), TG, FTIR, and scanning electron microscopy (SEM). The results showed that PDTA was synthesized as expected and was stable below 200 °C. The results also showed that when the loadings of ABS, APP, and PDTA were 70, 22.5, and 7.5 %, respectively, the LOI value reached 31 % and the UL-94 vertical burning test was V-0. What is more, even when the addition of IFR was decreased to 25 %, the LOI value of the ABS/APP/PDTA (75/18.75/6.25) system was 28 %, indicating compounding APP and PDTA could improve the flame-retardant performance of ABS. The FTIR indicated there was a chemical reaction between APP and PDTA to form a heat-resistant triazine ring, and SEM indicated the ABS/APP/PDTA systems had a denser char structure than that of pure ABS. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
