Polyethylene addition or condensation polymer
WebPoly(butylene terephthalate) (PBT) copolyesters modified with seven compositions of p-acetoxybenzoic acid (PABA) ranging from 10 to 70 mol % were prepared. The X-ray diffraction patterns, the polarizing microscopy behaviors, and thermal analysis showed that the modified PBT contained more PABA homopolymer units (PABA–PABA) than …
