Ring-opened polymers (A) obtained by ring-opening metathesis polymerization of pericyclic olefin(s) of the 4,7-alkano-1-oxo-isobenzofuran, -2-benzothiophene, isoindole, -isophosphindole, -indene or -2-silaindene type (I) and/or 4,9:5,8-dialkano-1-oxo-naphtho(2,3-c)-furan, -naphtho(2,3-c)thiophene, -benz(f)isoindole, -benz(f)isophosphindole, benz(f)indene or benz(f)silaindene type (II) are new. Ring-opened polymers (A) obtained by ring-opening metathesis polymerization of pericyclic olefin(s) of the 4,7-alkano-1-oxo-isobenzofuran, -2-benzothiophene, isoindole, -isophosphindole, -indene or -2-silaindene type of formula (I) and/or 4,9:5,8-dialkano-1-oxo-naphtho(2,3-c)-furan, -naphtho(2,3-c)thiophene, -benz(f)isoindole, -benz(f)isophosphindole, benz(f)indene or benz(f)silaindene type of formula (II) are new. A, B = hydrogen or a substituent; or AB = a (hetero)cyclic ring; C = oxygen, sulfur, =N-O-SO2-R<1>, -N-R<1>, -N-SO2-R<1>, -P-R<1>, -CH2- or -SiH2-; n = 1-6. The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for: (a) Ring-opened polymers (B) obtained by hydrogenation of polymer (A); (b) a thin film coating composition containing polymer (A) or (B); (c) a photosensitive composition containing polymer (A) or (B); and (d) a polymer blend containing polymer (A) or (B) and a different polymer.
