Figure 4 matches the tack strength performance of palm kernel oil alkyd resins as a tackifier in rabber compound againsta reference (the same ENR compound without alkyd), polyterpene (a 3-pinene resin with softening point of around 30°C) and petroleum resin (C5 type aliphatic hydrocarbon resin withsoftening point around 100°C), two of the very common tackifiers in the tire industry. These... 

Three different resin-rubber blend systems were examined by frequency scan at room temperature. First, we examined blends of natural rubber with a compatible aliphatic oil. Figure 44 shows G vs. frequency at various loadings of oil to natural rubber. As we add oil, the modulus curve as a function of frequency is depressed. This is to be expected as the oil softens the composition which, in turn, causes the reduction of the modulus. In other words, oil does not change the tan 8 peak (7g) temperature of natural rubber it only reduces the room-temperature modulus value of natural rubber. Consequently, it does not function as an effective tackifying resin.

Tackifying resins also come from petroleum feedstocks. These are broadly dassified as aromatic and aliphatic resins. The aromatic resins are based upon such materials as styrene, a-methyl styrene, methyl indene, indene, coumarone, and dicy-dopentadiene. Aromatic resins are sometimes called C-9 resins. The materials in various combinations are polymerized by much the same process as the pinenes. Some of the aliphatic resins are also called C-5 resins, as these are based upon pen-tene, cydopentene, ds- and tram-piperylene, isoprene, 2-methyl butene-2, and dicydopentadiene. An abbreviated list of conventional taddfying resins is shown in Table 1. 

Other natural product-based resins also became widely used, such as the light colored Lewis acid oligomerized products of terpenes such as a-pinene, p-pinene, and limonene. These natural product resins are relatively expensive, however, and formulators now often use the newer, less expensive synthetic resins in present day natural rubber PSAs. These are termed the aliphatic or C-5 resins and are Lewis acid oligomerized streams of predominately C-5 unsaturated monomers like cis- and /rawi-piperylene and 2-methyl-2-butenc [37]. These resins are generally low color products with compatibility and softening points similar to the natural product resins. Representative products in the marketplace would be Escorez 1304 and Wingtack 95. In most natural rubber PSA formulations, rubber constitutes about 100 parts and the tackifier about 75-150 parts. 

A more quantitative estimation of compatibility can be obtained with the solvent cloud point test. The solvent cloud point is based on the idea that resins will be compatible with elastomers of similar chemical nature. Thus aliphatic resins will be effective tackifiers for aliphatic elastomers, such as natural rubber, while aromatic solvents are needed for aromatic elastomers, such as SBR. Solvent cloud point tests are carried out in three solvent systems which represent aliphatic, aromatic, or polar systems [16j ... 

Tackifiers. The tackifiers usually are hydrocarbon resins (aliphatic C5, aromatic C9) or natural resins (polyterpenes, rosin and rosin derivates, tall oil rosin ester). They improve hot tack, wetting characteristics and open time and enhance adhesion. The content on tackifiers in a hot melt can be in the region of 10-25%.
