  • Can plasticizers reduce the migration of polymers?
  • Efforts have been made to reduce the reduction of the migration of plasticizers in polymers through using more complex and higher molecular weight plasticizers which entangle in the polymer matrix to prevent migration. However, there is the downside of ineffective plasticization with this method.
  • How do plasticizers change mechanical properties of a polymer?
  • Plasticizers are able to introduce new mechanical property changes when added into the matrix of the polymer as shown below in figure 1. The mechanism of action is termed plasticization. In addition, the mechanism of how the polymers are plasticized are described by theories which will be discussed in the later of this review.
  • Why are plasticizers used in polymers?
  • Sangmyung University Seoul, South Korea Abstract:- Plasticizers are chemical additives added into polymers to influence desirable mechanical properties such as processability and ductility. These properties are a result of the association of plasticizer and polymer molecules under the theories of plasticization.
  • How do plasticizers affect biodegradable polymers?
  • Plasticizers can control polymer degradation in biodegradable polymers and, depending on the additive, can either increase or decrease the biodegradation rate. In effect, the plasticizer creates a disposable biodegradable biopolymer. Plasticizers are valuable and essential to industries throughout the world today.
  • What happens if plasticizers are not chemically attached to polymer chains?
  • When plasticizers are not chemically attached to polymer chains at certain conditions, it leaves the polymer through migration (Mass transfer) which leads to undesirable property changes in the polymer and consequent contamination of the surrounding medium .
  • What is plasticizer migration?
  • Plasticizer migration refers to the undesired movement of a plasticizer outside a compound. The movement occurs through gas volatilization, liquid extraction, or solid migration. This phenomenon occurs when there is limited interaction between the polymer and the plasticizer.
