  High purity amino-1,3-benzenediols are prepared by (a) contacting a 1,3-bis(alkylcarbonato)benzene with a nitrating agent under reaction conditions such that a 1,3-bis(alkylcarbonato)nitrobenzene is formed, (b) con­tacting the 1,3-bis(alkylcarbonato)nitrobenzene with a hydrolyzing agent under conditions such that a nitro­-1,3-benzenediol is produced, and (c) contacting the nitro-1,3-benzenediol with a reducing agent under con­ditions such that an amino-1,3-benzenediol is produced. Of the amino-1,3-benzenediols, 4,6-diamino-1,3-benzene­diol is particularly useful in the preparation of high molecular weight polybenzoxazoles.

  高纯度氨基-1,3-苯二酚是通过以下方法制备的：(a) 将 1,3-双(烷基羰基)苯与硝化剂接触，在反应条件下生成 1,3-双(烷基羰基)硝基苯；(b) 将 1、(c) 将硝基-1,3-苯二酚与还原剂接触，生成氨基-1,3-苯二酚。在氨基-1,3-苯二酚中，4,6-二氨基-1,3-苯二酚尤其适用于制备高分子量的聚苯并噁唑。

  PROBLEMS The present invention relates to a process for producing a polybenzoxazole polymer and provides a process for producing the polybenzoxazole polymer within a short reaction time. MEANS FOR SOLVING PROBLEMS A process for producing a polybenzazole polymer comprises producing the polybenzazole polymer in a non-oxidizing dehydrating solvent while employing a compound represented by the following general formula (1) as a raw material including a first polymerization step in which polymerization is performed at a temperature of 150° C. or less and a latter polymerization step in which polymerization is performed at a temperature of 200° C. or more, wherein at least the latter polymerization step is performed in a kneading-type reaction apparatus to complete the polymerization reaction: wherein X represents an O atom, an S atom or an NH group; Ar 1 represents a tetravalent organic group having two or less of benzene rings, naphthalene rings or pyridine rings; Ar 2 represents a bivalent organic group having two or less of benzene rings, naphthalene rings or pyridine rings; both of Ar 1 and Ar 2 may have one or more functional groups such as a methyl group and a hydroxyl group; and R represents H or a univalent organic group with a carbon number of 1 to 6.
