Synthesis of novel plasticizer ester end-capped oligomeric
Furthermore, compared with ATBC and DOTP, EOLs showed better migration resistance in the leaching test. All test results showed that the comprehensive performance of EOLs was better than those of commercial green plasticizers ATBC and DOTP, which provided a new method for the development of novel green plasticizers.

- How are ester plasticizers selected?
- Ester plasticizers are selected based upon cost/performance evaluation. The rubber compounder must evaluate ester plasticizers for compatibility, processability, permanence and performance properties. The study of these properties by the rubber compounder will contribute to the selection of a high-performance ester plasticizer.

- What is a general performance ester plasticizer?
- Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length. Ester plasticizers are commonly used only for their as-molded, low-temperature contribution.
- Why do we use ester plasticizers?
- Ester plasticizers make it possible to process elastomers easily while also providing flexibility in the end-use product. Plasticizer–elastomer interaction is governed by many factors, such as solubility parameter, molecular weight and chemical structure. Ester plasticizers are selected based upon cost/performance evaluation.
- Which plasticizers are used in combination with specialty monomeric esters?
- Flame-retardant plasticizers, phosphate esters and chlorinated paraffins are often combined in usage with flame-retardant plasticizers frequently used in combination with specialty monomeric esters. Both materials are inefficient plasticizers, thus explaining their combinations with specialty monomerics.
- How are polymeric plasticizers produced?
- Polymeric plasticizers are produced by reacting a dibasic carboxylic acid with a glycol or a mixture of different dibasic glycols. When the molecules are reacted, the chain propagation or building may be terminated by the use of monofunctional carboxylic acids or alcohols. Some polymeric plasticizers are also produced using no terminator.
