Patent number: 6663970Abstract: The instant invention relates to an epoxy/alkylation-type hydrocarbon resin alloy comprising an epoxy resin, an alkylation-type hydrocarbon resin, and a curative. The alkylation-type hydrocarbon resin is characterized as a product formed by an alkylation reaction between a cyclic diolefin and aromatic solvent. A particularly effective alkylation-type hydrocarbon resin in this invention is the alkylation resin formed by the reaction of dicyclopentadiene (DCPD) with alkylnaphthalene solvent. The alkylation-type hydrocarbon resin can be readily dissolved into various epoxy resins and easily processed into resin impregnated glass cloth prepreg for ultimate conversion into electronic laminate products. These epoxy/alkylation-type hydrocarbon resin alloys retain high Tg values with minimal increase in thermal expansion.Type: GrantFiled: January 31, 1997Date of Patent: December 16, 2003Assignee: Eastman Chemical Resins Inc.Inventor: Daniel W.

Patent number: 6281290Abstract: Masterbatches comprising high density polyethylene (HDPE) are used for the production of polyolefin articles, particularly films. Employing HDPE in a masterbatch alone or in combination with a hydrocarbon resin and/or a polyolefin ultimately results in extruded polyolefin articles of optimal stiffness and ductility. Employing a high density polyethylene in combination with a hydrocarbon resin and a polyolefin in a masterbatch causes the masterbatch to solidify more rapidly and be pelletized more efficiently.Type: GrantFiled: February 25, 2000Date of Patent: August 28, 2001Assignee: Eastman Chemical CompanyInventor: Daniel W.

Patent number: 5391670Abstract: 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.Type: GrantFiled: August 9, 1993Date of Patent: February 21, 1995Assignee: Hercules IncorporatedInventors: Atanu Biswas, Daniel W.
