Versuchsvorschrift
Polymerization was carried out in the same way as Example 1, except that (A) preparing materials were changed to 4,4′-dihydroxybiphenyl, dodecanedioic acid, 4-hydroxybenzoic acid, acetic anhydride, and (B) a mixture of 4,4′-dihydroxybiphenyl, dodecanedioic acid, 4-hydroxybenzoic acid, acetic anhydride at a molar ratio of 1.05:1:2:4.1 in which 4,4′-dihydroxybiphenyl was excess by 5 mol % was prepared in a reactor vessel, thereby producing a thermoplastic resin in which 4-hydroxybenzoic acid was copolymerized with the resin of Example 1. A molecular structure, sealed end groups, and a sealing rate of ends are shown in Table 2, and changes in number average molecular mass and thermal conductivity before and after melting are shown in Table 3.
