Patent ID: 7009007

Claim:
A polymer represented by Structural Formula (1): [—P 1 —R—] n (1), wherein P 1 is an addition polymer moiety having a continuous hydrocarbon skeleton containing no condensation system and formed by addition polymerization of one or more monomers having a double bond; R is a linking moiety comprising a condensation system; and n is a number of repeating units and is an integer of 2 or more, wherein the linking moiety R is represented by Structural Formula (2): X 1 -A-X 2 (2), wherein X 1 and X 2 are the same atomic group linked to P 1 in the Structural formula (1), and selected from the group consisting of —CONH—, —NH—CO—O— and —NH—CO—NH—, and A is an atomic group capable of linking with X 1 and X 2 .
