The present disclosure relates to a process of manufacturing a moisture-curable adhesive composition, wherein the process comprises the steps of:
a) providing a multi-screw extruder comprising a reaction chamber;
b) providing reactants and reagents comprising:
i. at least one isocyanate;
ii. at least one amine; and
iii. optionally, at least one plasticizer;
c) incorporating the reactants and reagents into the reaction chamber of the multi-screw extruder, thereby forming a reaction product comprising a urea derivative; and
d) incorporating at least one moisture-curable prepolymer into the reaction product resulting from step c), thereby forming a moisture-curable adhesive composition.
In another aspect, the present disclosure is directed to a moisture-curable adhesive composition obtainable by the process as described above.
