| titleOfInvention | low molecular weight, light-colored, modified phenolic rosine esters |
| abstract | "LIGHT MOLECULAR MODIFIED-PHENOLIC ROSINE ESTERS, LIGHT-COLORED" light-colored modified-phenolic rosin esters suitable for use as, for example, tackiness builders in adhesive compositions, are provided. Resins can be prepared by reaction of rosin, a phenolic compound, formaldehyde or a reactive equivalent, and an organic compound containing non-phenolic hydroxyl in the presence of at least one color-reducing agent selected from phenol sulfide, phosphorous acid, phosphorous acid esters, and hypophosphite salts. Formaldehyde or reactive equivalent is present in an amount ranging from about 1.1 to about 3.5 equivalents of -CHO halves per 1 equivalent of Ar-OH half of the phenolic compound, in order to obtain rosin esters having desirably low color, and suitably low molecular weight to function effectively as stickiness builders. |
