FIGURE 9.8 Hydrogenated hydrocarbon resin styrene and methyl styrene monomers are polymerized to form an oligomer, which is then catalytically hydrogenated (e.g. Regalrez 1094). 

The hydrogenated hydrocarbon resin Regalrez 1094 has been used for saturating degraded paint films (Epley, 2000) and as a varnish component (Whitten, 1995). To counteract its inherent brittleness, a small amount of a stress-absorbing... 

Hydrocarbon resins based on CPD are used heavily in the adhesive and road marking industries derivatives of these resins are used in the production of printing inks. These resins may be produced catalyticaHy using typical carbocationic polymerization techniques, but the large majority of these resins are synthesized under thermal polymerization conditions. The rate constants for the Diels-Alder based dimerization of CPD to DCPD are weU known (49). The abiHty to polymerize without Lewis acid catalysis reduces the amount of aluminous water or other catalyst effluents/emissions that must be addressed from an environmental standpoint. Both thermal and catalyticaHy polymerized DCPD/CPD-based resins contain a high degree of unsaturation. Therefore, many of these resins are hydrogenated for certain appHcations. 

Triacetin resistance is especially critical when filter tips are made in one location, stored, and then shipped to another location. For these operations, polyethylene-based adhesives are used because of their low polarity and therefore excellent resistance to triacetin. Where filter plugs are attached at the same location shortly after production, EVA-based adhesives are suitable and preferred. Both types of adhesives use low odor, clean tackifiers such as hydrogenated hydrocarbons or pure monomer resins (typically a-methylstyrene based). Rosin, rosin esters, and phenol-containing tackifiers are not acceptable. EVA-based adhesives use a higher level of wax (about 1 /3 of the formula) than polyethylene-based adhesives (5-20% wax) due to the lower crystallinity and slower set of EVA vs. PE. Application viscosities are 2000-5000 cP. 

A hot melt adhesive composition has been described that contains two types of EVA, further a hydrogenated petroleum hydrocarbon resin. This resin is obtained from a petroleum feedstock followed by hydrogenation (25). 

This property depends upon the structure of the acrylic resin. Most of the resins are soluble in moderately hydrogen-bonded solvents (e.g. ketones, esters, chlorinated hydrocarbons and aromatic hydrocarbons). Resins with more alcohol chains have greater solubility in alcohols, aliphatic hydrocarbons and naphtha. 

Binary blends prepared by mixing iPP with a fully saturated ahcyclic hydrocarbon resin (obtained by cationic oligomerization of indene, a-methyl styrene, and vinyl toluene, followed by hydrogenation) showed good miscibihty in the melt state (12).
