A monomer represented by Chemical Formula (1): ##STR00001##
wherein, X, Y, and Z are the same as described in the specification, and the polymer including repeat units derived from the monomer.

A copolymer essentially consisting of: from 50 to 99 mole % of at least one recurring unit (R.sub.1), based on the total mole amount of the recurring units (R.sub.1) and (R.sub.2), wherein the recurring unit (R.sub.1) is derived from incorporation of 4,4-terphenyl-p-diol and a dihaloaryl sulfone compound and from 1 to 50 mole % of at least one recurring unit (R.sub.2), based on the total mole amount of the recurring units (R.sub.1) and (R.sub.2), wherein the recurring unit (R.sub.2) is derived from incorporation of 4,4-terphenyl-p-diol and a dihaloaryl ketone compound.

The present invention relates to a binder system containing a resin component and a curing agent component, wherein the resin comprises at least one compound carrying at least two cyclic carbonate groups and at least one compound carrying at least two epoxy groups, and the curing agent comprises at least one multifunctional amine as well as the use of the binder system as an adhesive/sealant and the use of this adhesive/sealant.

Provided is a synthesis method comprising a first step of producing a carbonate compound from carbon monoxide and an alcohol-based compound at an anode of a first electrochemical cell comprising a cathode and the anode, and a second step of synthesizing a first product by a dealcoholization reaction of the carbonate compound, wherein an alcohol-based compound eliminated in the second step is recycled in the first step.
