Abstract
The invention relates to a curable composition and a process of preparing the curable composition. The process comprises (a) forming an oligomer from oligomerization of a mixture of a monomer A having a functional group and a monomer B at a temperature in the range of from 150° C. to 650° C., a pressure in the range of from 3 MPa to 35 MPa and the pressure is high enough to maintain the reaction mixture in a fluid state and a residence time in the range of from 0.1 second to 4 minutes; and (b) reacting a modifier having at least one reactive moiety with the oligomer through a reaction between the reactive moiety of the modifier and the functional group of the monomer A in the oligomer, and the modifier further comprises a curable group.
