    摘要: A caddy assembly for carrying a fishing rod includes a tripod that may be positioned on a support surface. A head is movably coupled to the tripod. The head is positionable at a selected angle with respect to the tripod. A handle is coupled to the head. The handle may be gripped. A carrier is coupled to the head. The carrier may carry a fishing rod.

    摘要: AB-polybenzoxazole monomer, such as 3-amino-4-hydroxybenzoic acid, can be synthesized in high yields from a hydroxy-benzoic acid or related compound in a three-step process of (1) nitration, (2) hydrolysis of the ester, and (3) reduction of the nitro moiety. The monomer is conveniently recovered as a phosphate salt in high purity by precipitating and recrystallizing from a phosphoric acid solution. The monomer may be polymerized in high concentrations in polyphosphoric acid containing high levels of P.sub.2 O.sub.5 to yield a high molecular weight polymer without dehydrohalogenation.
