[0051] The addition of silicone resin to the silicone-acrylic copolymer is considered as a "bodying reacting" and is con› ducted in the presence of a bodying catalyst. Examples of the bodying catalyst for this bodying reaction is (NH$_{4}$ ) $_{2}$CO$_{3}$(s), ammonium carbamate, NH$_{4}$OH(aq), methanesulfonic acid, sulfuric acid, acidic clay, acidic Amberlyst™ ion exchange resins (Rohm and Haas), KOH, NaOH, LiOH, n-BuLi, and mixtures thereof. While the bodying reactions may take place at room temperature, one preferred method is to conduct the reaction with heating at 50-160° C. The preferable tempera› ture of the bodying step is between 40-150° C. 

[0052] The bodying reaction is preferably allowed to pro› ceed at least until the rate of evolution of condensation byproducts, such as water, alcohol, and carbodioxide, is sub› stantially removed. Heating can be continued until the desired physical properties such as viscosity, clarity of the solution, and adhesion values are obtained. Typically the mixture of each step will be allowed to react from about 1 to about 24 hours. When the bodying step of reaction is complete, the solids content of the resulting composition can be adjusted by adding or removing solvent. 

[0053] Suitable tackifying agents are those known in the art including: (1) aliphatic hydrocarbons; (2) mixed aliphatic and aromatic hydrocarbons; (3) aromatic hydrocarbons; (4) sub› stituted aromatic hydrocarbons; (5) hydrogenated esters; (6) polyterpenes; (7) mineral oils; and (8) wood resins or rosins and hydrogenated forms thereof. Useful levels of tackifiers are generally from about 1 wt% to about 30 wt% based on the weight of the total composition. 

[0054] The copolymers of the invention may also be blended with additional polymers to enhance desired proper› ties. Examples of polymers useful for blending include, but are not limited to, other acrylates, polysiloxanes, polyisobu› tylene, polyester, PPO, polyisoprene, polybutadiene, styrenic block polymers, and the like. Examples of styrenic block copolymers include, but are not limited to, styrene-isoprene› styrene block copolymer (SIS), styrene-butadiene-styrene copolymer (SBS), styrene-ethylenebutene-styrene copoly› mers (SEBS), and diblock analogs thereof. 

[0055] The compositions of the invention may include other additives known to those skilled in the art. These addi› tives may include, but are not limited to, pigments, fillers, fluorescent additives, flow and leveling additives, wetting agents, surfactants, antifoaming agents, rheology modifiers, permeation enhancers, stabilizers, and antioxidants. 

[0056] Antioxidants may be added singly or in combination to protect the components against degradation during prepa› ration and use of the adhesive compositions, and to ensure long-term thermal stability. In general up to about 1 % by weight of one or more antioxidants may be included in the adhesive compositions, usually, from about 0.1 % to about 0.5% by weight. 

[0057] Additional polymers may be further blended with the silicone-acrylic copolymers. Examples of such polymer include polyester, polyether, polyurethane, natural rubber, synthetic rubber, and the like.
