Abstract

A compound of formula (I) <img class="EMIRef" id="3af7b261-65f2-4693-969d-39536a5b9f0a-ia01" /> wherein R<1> and R<2> are independently H, C<1>-C<18>-alkyl or C<1>-C<18>-alkoxy, which alkyl and/or alkoxy is unsubstituted or substituted with at least one substituent R<3>, R<3> is independently halogen, hydroxyl, C<1>-C<18>-alkoxy, Cs-Cs-cycloalkyl, Cs-Cs-cycloalkoxy, 3 to 8-membered heterocycloalkyl, 3 to 8-membered heterocycloalkoxy, C<5>-C<10>-aryl, C<5>-C<10>-aryloxy, 3 to 8-membered hetaryl or 3 to 8-membered hetaryloxy, which alkoxy, cycloalkyl, cycloalkoxy, heterocycloalkyl, heterocycloalkoxy, aryl, aryloxy, hetaryl or hetaryloxy may be unsubstituted or substituted, - - - denotes a single bond or a double bond, and with the proviso that the compound in which R<1> is H and R<2> is H is excluded is a lignin derived monomer that is capable of self-polymerization. Polymers are obtained from the compound of formula (I) where the 7-membered ring contains an olefinic unsaturation by ring-opening metathesis polymerization. Polymers are obtained from the compound of formula (I) where the 7-membered ring contains no olefinic unsaturation by ring-opening polymerization.
