Biodegradability and biocompatibility of copoly(butylene sebacate-co-terephthalate)s [PDF]
, 2017 In the present study poly (butylene sebacate-co-terephthalate)s having different compositions were synthesized with a high yield and a random distribution by thermal transesterification of poly (butylene sebacate) and poly (butylene terephthalate ...

Effect of hydroxyapatite nanoparticles on the degradability of random poly(butylene terephthalate-co-aliphatic dicarboxylate)s having a high content of terephthalic units [PDF]
, 2016 Copolyesters derived from 1,4-butanediol and constituted also of aliphatic and aromatic dicarboxylate units in a molar ratio of 3:7 were synthesized by a two-step polycondensation procedure.

Characterization of New H-Bonded Liquid Crystalline Complexes Based on Iminophenyl Nicotinate
Crystals, 2020 Two new 1:2 supramolecular H-bonded liquid crystalline complexes (SMHBCs) were prepared through double H-bond interactions between either isophthalic acid (A) or terephthalic acid (B) and a nicotinate Schiff base (I6). The formed complexes were thermally

Commercial fire-retarded PET formulations - relationship between thermal degradation behaviour and fire-retardant action [PDF]
, 2007 Many types of fire-retardants are used in poly(ethylene terephthalate), PET, formulations, and two commercial fire retardants, Ukanol(TM) and Phosgard(TM), have been shown to improve significantly PET flame-retardancy when used as comonomers.

Pivalolactone, 1 interchange reactions with polypivalolactone [PDF]
, 1993 Ester interchange, alcoholysis, and acidolysis of polypivalolactone (PPVL) were studied by melting PPVL with bisphenol diacetates, 1, 4-butanediol, or aromatic diacids.

Chemical and Pharmaceutical Bulletin, 1968 The acute toxicity of terephthalic acid and its sodium salt, the effect of terephthalic acid administration on liver and renal functions, and the chemical composition of blood plasma were studied. LD50 of terephthalic acid in mice was found to be more than 5000 mg/kg by oral administration and 1430 mg/kg by intraperitoneal injection.
