Polyquinazolines and their method of manufacture

Abstract

Abstract THE POLYQUINAZOLINES CONTAIN IN THEIR CHAINS QUINAZOLINE NUCLEI OF THE FORMULA: BENZOPYRIMIDINE IN WHICH THE "BENZO" MOIETY IS A R1-BENZENE NUCLEUS. R1 IS HYDROGEN OR ONE OF SEVERAL LOWER ALKYL SUBSTITUENTS, LOWER ALKOXYL OR HALOGEN AT ONE OR SEVERAL OF THE FREE POSITIONS ON THE RING. THESE QUINAZOLINE NUCLEI ARE LINKED, EITHER AT THEIR 2-POSITIONS THROUGH A DIRECT LINKAGE OR AN ARYLENE GROUP AND AT THEIR 4-POSITIONS THROUGH AN ARYLENE, ALKYLENE OR ALKYLARYLENE GROUP; OR AT THEIR 2-POSITIONS THROUGH AN ARYLENE GROUP AND AT ONE AT THEIR 5-, 6-, 7- AND 8-POSITIONS, THROUGH A DIRECT LINKAGE OR A SHORT CHAIN OR HETERATOMIC BIVALENT RADICAL, SUCH AS -CH2-, -CO-, -O-, -SO2-, -S-; THE QUINAZOLINE NUCLEI OF THE POLYQUINAZOLINES THUS OBTAINED BEARING AN ALIPHATIC OR AROMATIC RADICAL P, AT THEIR 4-POSITIONS, OR AT THEIR 4-POSITIONS THROUGH A DIRECT LINKAGE OR THROUGH AN ARYLENE, ALKYLENE OR ARALKYLENE GROUP AND AT ONE OF THEIR 5-, 6-, 7-, 8-POSITIONS, DIRECTLY OR THROUGH A SHORT CHAIN OR HETERATOMIC BIVALENT RADICAL, SUCH AS -CH2-, -CO-, -O-, -SO2-, OR -S-; THE QUINAZOLINE NUCLEI OF THEPOLYQUINAZOLINES THEN OBTAINED BEARING AN AROMATIC RADICAL Q AT THEIR 2-POSITIONS.
