A tackifier resin is provided comprising monomer units from at least one aromatic monomer and at least one acrylate monomer; wherein the tackifier resin has a low residual monomer concentration. In other embodiments of the invention, the tackifier resin does not significantly decrease the moisture vapor transport rate of an adhesive composition comprising the tackifier resin, does not significantly increase fogging of an adhesive composition comprising the tackifier resin, and does not significantly exhibit skin sensitivity properties. A process to produce the tackifier resin is also provided. The process comprises contacting a tackifier resin product stream with at least one carrier at a temperature sufficient to remove a portion of at least one residual monomer from the tackifier resin product stream to produce the tackifier resin.

Aromatic-acrylate tackifier resins

An adhesive composition comprising at least one tackifier resin and at least one acrylic polymer is provided wherein the tackifier resin comprises monomer repeating units from at least one aromatic monomer and at least one acrylate monomer; and wherein the tackifier resin has a low residual monomer concentration. Processes to produce the adhesive composition is also provided.

Aromatic/acrylate tackifier resin and acrylic polymer blends

A radiation-curable adhesive composition comprising at least one tackifier resin and at least one radiation-curable composition is provided wherein the tackifier resin comprises monomer repeating units from at least one aromatic monomer and at least one acrylate monomer. Processes to produce the radiation-curable adhesive composition as well as articles comprising the radiation-curable adhesive compositions are also provided.

Radiation-curable adhesive compositions

Acid modified C hydrocarbon resins are disclosed. The resins are predominantly piperylene resins with isobutylene. The resins are acid modified with from about 0.1 to 30 weight percent maleic anhydride to provide an acid-modified resin with a acid number from about 30 to about 170 mg KOH/g resin. The acid-modified resins have a mettler drop softening point from about 40&deg; C. to about 140&deg; C. The acid modified resins are useful as a natural rosin alternative.
