Abstract:
1. A method for manufacturing reactive end capped resins or adhesives, comprising: dissolving at least one dichloroaromatic monomer and at least one monochloroaromatic protected end cap in a dipolar aprotic solvent; adding at least one reducing metal reagent and one transition metal catalyst to create a first mixture; heating said first mixture for 1-12 h at a temperature between about 25 to about 100° C. to create a second mixture; filtering said second mixture to produce a third mixture; adding said third mixture to a non-solvent forming a protected resin, and collecting said protected resin by filtration; drying said protected resin at 25 to 100° C. for 24-48 h to produce a dried protected end capped resins or adhesives; deprotecting said dried protected end capped resins or adhesives; and reacting said deprotected end capped resins with a nitrogen including aromatic electrophile to produce reactive end capped resins or adhesives.
