WHAT ARE HYDROCARBON RESINS?
•
LOW MOLECULAR WEIGHT, AMORPHOUS, THERMOPLASTIC POLYMERS DERIVED FROM SYNTHETIC OR NATURAL MONOMERS TYPE TYPICAL MONOMERS
WHERE DO HYDROCARBON RESINS COME FROM?
• FIRST EXAMPLES FROM COAL TAR DISTILLATES IN 1920’s - Mixed Aromatic Monomers / BF3 Polymerization - Coumarone-Indene Resins • TERPENE BASED RESINS HAVE BEEN AVAILABLE SINCE THE MID-1930’s - Citrus Oils / d-Limonene - Sulfate Turpentine / a -Pinene, b-Pinene, Dipentene • MONOMERS FROM CRACKED PETROLEUM DISTILLATES APPEARED IN 1940’s - Aliphatic Olefins / Diolefins, C5-C6 - Vinyl Aromatics, C8-C10 - Cyclodiene Dimers, C10-C12 • SYNTHETIC AROMATIC MONOMERS ALSO AVAILABLE Styrene Vinyl Toluene Para-Methyl Styrene a-Methyl Styrene

PRIMARY FUNCTIONS OF TACKIFYING RESINS
• Compatible with Adhesive Polymer-- Not a Filler • Lowers Average Molecular Weight-- Viscosity Adjustment • Raises the Blended Tg-- Not a Plasticizer, Improves adhesion
