A biodegradable fiber that is formed from a thermoplastic composition that contains polylactic acid, a plasticizer, and a compatibilizer is provided. The compatibilizer includes a polymer that is modified with a polar compound that is compatible with the plasticizer and a non-polar component provided by the polymer backbone that is compatible with polylactic acid. Such functionalized polymers may thus stabilize each of the polymer phases and reduce plasticizer migration. By reducing the plasticizer migration, the composition may remain ductile and soft. Further, addition of the functionalized polymer may also promote improved bonding and initiate crystallization faster than conventional polylactic acid fibers. The polar compound includes an organic acid, an anhydride of an organic acid, an amide of an organic acid, or a combination thereof. Such compounds are believed to be more compatible with the generally acidic nature of the polylactic acid fibers.

Liquid Crystalline Polymer Composition for High Voltage Electronic Components

Номер: US20130123420A1

Автор: Kim Young Shin

Принадлежит: Ticona LLC

A liquid crystalline polymer composition having a relatively high comparative tracking index (“CTI”) is provided. The present inventors have discovered that high CTI values can be achieved through the use of inorganic particles in combination with a functional aromatic compound. While not fully understood, it is believed that the functional compound can react with the liquid crystalline polymer and create smaller degraded polymer chains. In combination with the inorganic particles, these smaller chains can potentially form insulated regions at the surface of the polymer that hinder the formation of conductive carbonaceous deposits during the tracking process, which could otherwise lead to failure during testing. 2. The polymer composition of claim 1 , wherein the functional aromatic compound includes a phenolic compound claim 1 , diphenolic compound claim 1 , naphthenic compound claim 1 , or a combination thereof.3.
