Abstract: Synthetic resins suitable for use in printing ink compositions are described comprising (a) a predominant amount of dicyclopentadiene and lesser amounts of (b) at least one member selected from the group consisting of dimerized aliphatic, cyclic, and non-cyclic dienes of five carbon atoms; debutanized aromatic concentrates; C-5 olefins; acyclic conjugated C-5 dienes; mono-olefins, diolefins and polyenes each having more than five carbon atoms and having no aromatic rings, (c) at least one member selected from the group consisting of tall oil; fatty acid-containing materials and rosin acid-containing materials, (d) at least one ethylenically unsaturated lower aliphatic dicarboxylic acid or anhydride, and (e) at least one member selected from the group consisting of materials containing two or more reactive groups, at least one of which must be a hydroxyl group.

Abstract: Synthetic resins suitable for use in printing ink compositions are produced by reacting a mixture consisting essentially of (a) a predominant amount of dicyclopentadiene and lesser amounts of (b) at least one hydrocarbon selected from the group consisting of monoolefins, diolefins, and polyenes each having more than five carbon atoms, and having no aromatic rings, and (c) at least one member selected from the group consisting of fatty acid-containing materials and rosin acid-containing materials. Additional synthetic resins suitable for use in printing ink compositions are produced by reacting components (a) to (c) above with an ethylenically unsaturated lower aliphatic dicarboxylic acid or anhydride, such as maleic anhydride.

Abstract: An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formulations when incorporated as a plasticizer therein. Paraffins or alpha-olefins containing from 16 to 20 carbon atoms per molecule or mixtures or blends of paraffins or alpha-olefins containing 16 to 20 carbon atoms per molecule are chlorinated to a final chlorine content of from between 52 and 58 weight percent chlorine. The chlorinated hydrocarbons are compatible with polysulfide rubber sealant formulations while still maintaining the necessary low viscosity and volatility when incorporated as a plasticizer therein. A modified polysulfide rubber sealant formulation is disclosed which incorporates as a plasticizer the improved chlorinated hydrocarbon, and which is useful as a glass or window sealant. The improved plasticizer is non-fogging in a polysulfide rubber formulation.

Abstract: An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formulations when incorporated as a plasticizer therein. Certain paraffins or alpha-olefins and blends thereof when chlorinated to selected final chlorine contents are compatible with polysulfide rubber sealant formulations while still maintaining the necessary low viscosity and volatility when incorporated as a plasticizer therein. The improved plasticizers are not subject to significant heat loss. Modified polysulfide rubber sealant formulations are disclosed which incorporate as a plasticizer the improved chlorinated hydrocarbon, and which are useful as glass or window sealants, particularly as glass or window sealants between the panes of a thermal pane or multi-pane insulating window structure. The improved plasticizers are non-fogging in polysulfide rubber formulations and are not subject to significant heat loss.

Abstract: Synthetic resins suitable for use in printing ink compositions are produced by typically forming a base resin by polymerizing a reaction mixture consisting essentially of (a) a predominant amount of dicyclopentadiene and lesser amounts of (b) at least one hydrocarbon-containing material selected from the group consisting of debutanized aromatic concentrates, C.sub.5 olefins and acyclic, conjugated C.sub.5 dienes, and (c) at least one member selected from the group consisting of fatty acid-containing materials and rosin acid-containing materials. The base resin may be modified through a reaction with an ethylenically unsaturated lower aliphatic dicarboxylic acid or anhydride, such as maleic anhydride.

Abstract: Highly soluble solid resinous highly chlorinated alpha-olefinic hydrocarbon material contains above about 65% chlorine, has a ring and ball softening point of above about 90.degree. C, and is completely soluble and gel-free initially and after 24 hours in xylene (50% solution).

Abstract: Ethyl cellulose-compatible phenol-modified hydrocarbon resins are produced by polymerizing a reaction mixture containing indene, vinyl toluene, and dicyclopentadiene as the essential polymerizable constituents in the presence of a phenol compound and a Friedel-Crafts type catalyst such as boron trifluoride phenol complex. The phenol-modified hydrocarbon resin has a ring and ball softening point of above about 120.degree. C, a solution viscosity (Gardner-Holdt, sec.) of between about 0.7 and about 15, a hydroxyl number of above about 10, and is ethyl hydroxyethyl cellulose compatible as well as ethyl cellulose compatible. Thus, these resins are particularly useful as replacements for rosin and rosin derivatives in rotogravure printing ink.
