Poly p-hydroxybenzoic acid-co-ethylene

Figure 9.17 WAXS pattern at 25 C A = 154.18 pm (CuKa). Correlation of the WAXS peaks with the components in poly(p-hydroxybenzoic acid-co-ethylene terephthalate) (a) poly(p-hydroxybenzoic acid), a highly crystalline material (b) COP, 18h at 210-220 C and 4 MPa (c) PET, 60 min at 210-220 C and 4 MPa.

Injection molded bars of longitudinal PLC (poly(p-hydroxybenzoic acid-co-ethylene terephthalate) X7G ) showed a layered morphology [53]. Thinner specimens, of the order of 3 mm thick, showed three different layers symmetrically around the central plane of the specimen an oriented skin (s 0.5 Young s modulus at 23 C 15 GPa), an oriented layer beneath the skin (5 0.5-0.6 Young s modulus at...
