Abstract:
Polyester plasticizer compositions for adhesives, caulk, sealants, vinyl and other polymeric compositions comprising low molecular weight oligomeric dibenzoates prepared by end-capping a polyester plasticizer, having alternating units of glycols or diols and dibasic acids, with benzoic acid. Methods for preparing oligomeric dibenzoates include steps to reduce or eliminate residual hydroxyl content and improve plasticizer performance by adding acetic anhydride are also disclosed. Propylene glycol adipate and propylene glycol succinate polyesters with benzoic acid end-caps are particularly useful, as are hybrid benzoate/acetate end-capped polyesters formed in the process with acetic anhydride. Caulks, adhesives, sealants, and vinyl compositions comprising the oligomeric end-capped polyesters of the invention are also contemplated.
Abstract:
Unique 3-PPB monobenzoate analogs useful as plasticizers in polymeric dispersions, such as plastisols, melt compounds, and adhesives among other applications. The analogs are structurally similar to and/or derived from 3-phenylpropyl benzoate and heretofore were not known for use in industrial applications, particularly not as a plasticizer in polymeric applications. Depending on the application, the advantages rendered by the use of the inventive monobenzoate analogs include, among other things, excellent solvating properties and rheology, low viscosity and significantly improved viscosity over time, comparable or improved Tg suppression, set and open times, as well as health, safety and environmental advantages, over traditional plasticizers.
Abstract:
A unique monobenzoate useful as a plasticizer in polymeric dispersions, such as adhesives, comprising 3-phenyl propyl benzoate, a monobenzoate ester used as a flavor and fragrance additive, but not heretofore utilized as a plasticizer for polymeric dispersions, such as adhesives, caulks and sealants. The inventive monobenzoate provides a suitable non-phthalate, lower VOC alternative plasticizer that is compatible with a wide variety of polymers. Advantages rendered by the use of the inventive monobenzoate include, among other things, excellent viscosity response, low viscosity, viscosity stability, improved rheology, good film formation and comparable or better adhesion, peel strength, set time, open time, chalk point and MFFT, compared with that achieved by traditional plasticizers. The inventive monobenzoate also has an excellent health, safety and environmental profile and provides a viable alternative for adhesives used in food contact applications, such as packaging, where migratory concerns are an issue.
Abstract:
Plasticizer blends comprise a triblend of diethylene glycol dibenzoate, dipropylene glycol dibenzoate, and 1,2-propylene glycol dibenzoate, in specified ratios, useful in combination with a multitude of thermoplastic polymers, thermosetting polymers, and elastomeric polymers and numerous applications, including but not limited to plastisols, adhesives, sealants, caulks, architectural coatings, industrial coatings, OEM coatings, inks, overprint varnishes, polishes, and the like. The advantages rendered by the use of the triblend depend on the type of polymer and application in which it is utilized and include among other advantages higher solvating power and lower processing time, low VOC's, reduced plasticizer freeze point, improved gelation and fusion characteristics, higher tensile strength, superior stain and extraction resistance, and improved rheology over traditional diblends of diethylene glycol dibenzoate and dipropylene glycol dibenzoate.
