Methods for producing crosslinkable oligomers

摘要

Disclosed is a process for the preparation of crosslinkable oligomers comprising reacting at least one monomer having the structure VHC=CHX (I), and at least one monomer having the structure WHC=CYZ (II), wherein V, W, X and Z are defined in the specification, to form a reaction mixture; wherein the amount of the monomer or monomers of type (II) in the reaction mixture is between 55 mole % and 90 mole % based on the total number of moles of type (I) and type (II) monomers being reacted; and wherein more than 60 mole % of the monomer or monomers of type (I) have a side group containing at least one crosslinkable functional moiety and in which process throughout the reaction a pressure is maintained sufficient to maintain the monomers of type (I) and (II) in a substantially liquid phase and a temperature is maintained between 170ºC and 260ºC
