Epoxidized linolenic acid salts as multifunctional additives for the thermal stability of plasticized PVC

Abstract

Calcium and zinc salts of epoxidized linolenic acid were synthesized and used as multifunctional additives, to minimize or prevent the reaction of epoxidized soybean oil (ESO) with liberated hydrochloric acid (HCl) during the thermal degradation of poly(vinyl chloride) (PVC) in particular. These metal epoxy salts were incorporated as thermal stabilizers for both diisodecyl phthalate and ESO–plasticized PVC blends that underwent thermal degradation studies at 170°C. The overall performance of these metal epoxy salts was examined by thermal gravimetric analysis and visual color retention of the PVC blends. The weight loss profiles of the metal salt stabilized PVC were comparable to those of blends containing metal stearates. There were, however, vast improvements in color retention of the plasticized PVC using these novel additives. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41736.

The effect of maleinized linseed oil as biobased plasticizer in poly(lactic acid)‐based formulations

“…They can readily be converted into their corresponding epoxidized oils by epoxidation, leading to materials with potential use as biobased plasticizers and matrices for green composites. Several epoxidized vegetable oils such as epoxidized linseed oil, epoxidized soybean oil (ESBO), epoxidized castor oil, epoxy octyl stearate and epoxidized cottonseed oil have been reported as environmentally friendly plasticizers for a wide variety of polymers . The use of monomeric and polymeric plasticizers has also been reported in the last decade.…”

Ester‐amide based on ricinoleic acid as a novel primary plasticizer for poly(vinyl chloride)

“…11 Plasticizers can be either a primary or a secondary plasticizer. 23 Nihul et al investigated the effect of epoxidized rice bran oil (ERBO) as coplasticizer for PVC. Secondary plasticizers have limited compatibility with the PVC polymer chains and thus do not help PVC become flexible or soft as required.…”

Absorption and migration of bio‐based epoxidized soybean oil and its mixtures with tri(2‐ethylhexyl) trimellitate in poly(vinylchloride)

“…Note that the metal soap used herein was of a type that is particularly effective at stabilizing ESO plasticized PVC compositions . Furthermore, other newer thermal stabilizers have also been shown to be useful in such systems …”
