A hydrocarbon resin is prepared by (1) thermally polymerizing a mixture consisting essentially of (a) about 5% to 25% by weight styrene or aliphatic or aromatic substituted styrene, and (b) about 95% to 75% by weight based on total monomer content of a cyclic diolefin component comprising at least about 50% by weight dicyclopentadiene. A method of producing an aromatic-modified resin having a Mz of less than 2000 through the addition of about 5% to 25% by weight styrene in combination with about 95% to about 75% DCPD monomer at a rate to consume styrene monomer at a the rate at which it is added. Hydrogenation of this resin produces light colored, thermally stable products that are useful as tackifiers in adhesives.

The alkylation resins of this invention comprise the alkylation reaction product of (a) at least one substituted or unsubstituted polycyclic aromatic compound and (b) at least one ethylenically unsaturated hydrocarbon monomer having at least two carbon-carbon double bonds that reacts with the polycyclic aromatic compound by alkylation in the presence of an acid catalyst, wherein the ratio of (a) to (b) in the resin is about 1:9 to about 3:1 by weight. The resins have a weight average molecular weight of less than 10,000 measured by size exclusion chromatography, and a Ring & Ball softening point of about 50. degree. to about 250. degree. C. Because of their high softening point and low molecular weight, the resins are useful in a variety of applications such as flow rate modifiers for engineering polymers, tackifiers for adhesives, and flushing agents for inks.

Novel compounds are provided which exhibit high levels of anti-parasitic activity, specifically against parasites of the genus Trypanosoma. The compounds are comprised of aryl-substituted quaternary heteroaromatic salts which include a positively charged imidazolium or other heterocyclic ring, a linking group, a phenyl ring, and a polar functional group. The polar functional group is preferably a quanylhydrazone or a heterocyclic hydrazone. A method is also provided for treating the diseases associated with Trypanosoma parasites which comprises administering to infected animals or humans an effective amount of a compound of the present invention.
