Eects of molecular design parameters on plasticizer
Other types of plasticizers, such as adipates11–13, trimellitates13–15, phosphates2,16, epoxides16,17, and citrates11,16,18, are also commercially available. Many are considered as alterna- tives to phthalates. Development of new green plasticizers is also an area of strong interest7,19–21.
Dialkyl Succinates and Adipates as Alternative Plasticizers
This work presents a synthetic method for alternative plasticizers (dialkyl succinates and adipates) via esterification of succinic and adipic acid with alcohols: butan-1-ol and 2-ethylhexan-1-ol. Ionic liquids were synthesized by the reaction of triethylamine with over-equimolar (1:2.7) amounts of sulfuric(VI) acid, which were used as an

Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.

- Why are Adipates used as PVC plasticizers?
- Adipic acid esters are widely used as PVC plasticizers due to their good performance at low temperatures and their lower viscosity than phthalate plasticizers. The most frequently used adipates have chain lengths up to C10, with longer chains becoming physicochemically incompatible with many polymers .
- What is the best plasticizer for phthalate esters?
- Dialkyl succinates with longer alkyl chains, e.g., DOS, are the most effective plasticizers with similar or even better plasticizing properties than phthalate esters, having a high compatibility with the polymers that allows a high plasticization efficiency.
- Are adipate plasticizers safe?
- adipate plasticizers are a safe alternative. Ecotoxicity studies of the industrial plasticizer dioctyl adipate have confirmed its safety for living organisms [ 34 – 36 ]. environmental safety. 2. Results
- Can alkylbutoxyethyl adipates be used as PVC plasticizers?
- Earlier in work, alkylbutoxyethyl adipates were obtained, their characteristics, important for practical use as PVC plasticizers, were investigated . ... ... Expanding the range of biodegradable additives is a topical effective way to increase the biodegradation of PVC composites.
- Why are adipate plasticizers better than phthalates?
- The group of adipate plasticizers is characterized by a significant improvement in the flexibility of the material at low temperatures, which is due to the linear structure of the molecule and results in a lower viscosity of adipates as compared to phthalates and other plasticizers [11,12].
- Is dustrial plasticizer Dioctyl adipate safe?
- dustrial plasticizer dioctyl adipate have confirmed it s safety for living organisms [34–36]. ronmental safety. 2. Results 2.1. Synthesis of Butoxyethanol Ethoxylation of alcohols has been well st udied [37,38] (Scheme 1). The synthesis and characteristics of the product are desc ribed in our previous works [39,40]. Scheme 1.
