First claim

Opening claim text (preview).

We claim: 1. A phosphorus-containing polyamide of general formula (PA): wherein, A is one of —O— and R 1 -R 4 are each selected from the group consisting of hydrogen atom, C 1 -C 6 alkyl, C 1 -C 6 alkoxy, C 1 -C 6 haloalkyl, C 3 -C 7 cycloalkyl, —CF 3 , —OCF 3 , and halogen atom, m is an integer of 1-4, Ar′ is selected from the group consisting of and n is an integer of 30-300. 2. The phosphorus-containing polyamide of formula (PA) according to claim 1 , wherein when A is —O—, R 1 -R 4 are hydrogen atoms, and Ar′ is phenyl, the phosphorus-containing polyamide of formula (PA) is of formula (HPP-PA) 3. A process of preparing the phosphorus-containing polyamide of formula (PA): wherein, Ar′ is selected from the group consisting of and n is an integer of 30-300; comprising reacting a compound of formula (I) with a diacid compound of formula (IV) in a solvent to produce a phosphorus-containing polyamide of formula (PA), HOOC—Ar′—COOH   (IV) wherein Ar′ is defined as above, wherein in the compound of chemical formula (I) formula: R 1 -R 4 are each selected from the group consisting of hydrogen atom, C 1 -C 6 alkyl, C 1 -C 6 alkoxy, C 1 -C 6 haloalkyl, C 3 -C 7 cycloalkyl, —CF 3 , —OCF 3 , and halogen atom; A is one of —O— and Q is selected from the group consisting of —NO 2 , —NH 2 , and and m is an integer of 1-4. 4. The process according to claim 3 , wherein the solvent is N-methyl-pyrrolidone (NMP). 5. The process according to claim 3 , wherein calcium chloride is used in the reaction. 6. The process according to claim 3 , wherein triphenyl phosphite (TPP) is used in the reaction. 7. The phosphorus-containing polyamide of formula (PA) according to claim 1 , which is used in a flexible printed circuit board material.
