Procedure

Process according to claim 7, characterized in that 4,4'-diacetoxy-biphenyl, p-acetoxy-benzoic acid and 2,6-acetoxy-naphthoic acid are formed by means of the reaction of acetin anhydride with 4,4'-dihydroxybiphenyl, with p-hydroxy-benzoic acid and with 2,6-hydroxy-naphthoic, acid by heating to about 140° C., prior to the polymerization, within the same polymerization medium.
