Abstract
Novel solid benzoate ester compositions are mixtures comprising the trans- and cis-structural isomers of 1,4-cyclohexanedimethanol dibenzoate wherein the trans isomer constitutes from 1 to 66 or from 72 to 99 weight percent of the mixture. The properties imparted to a variety of polymer compositions, including hot melt adhesives, cannot be achieved using the commercially available mixture of these isomers.
Claims4
A method for accelerating a set time and crystallization rate of a hot melt adhesive composition comprising selecting a modifier comprising 1,4-cyclohexanedimethanol dibenzoate containing 90 to 94 weight percent trans isomer and formulating said hot melt adhesive composition comprising said modifier, a tackifying resin, and a thermoplastic polymer, wherein said tackifying resin is selected from the group consisting of rosin esters, aliphatic resins, and aromatic resins and said thermoplastic polymer is selected from the group consisting of ethylene/vinyl acetate copolymers, polyolefins, and styrenic block copolymers.
