Translucent thermoplastic elastomers.U.S. patent: 7,094,837 Issued: August 22, 2006 Inventors: Maria D. Ellul and Donald R. Hazelton Assigned: ExxonMobil Chemical Patents Key statement: Thermoplastic elastomers Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. of optical translucence are provided by incorporating syndiotactic A syndiotactic macromolecule in polymer chemistry is a tacticity essentially comprising alternating enantiomeric configurational base units which have chiral or prochiral atoms in the main chain in a unique arrangement with respect to their adjacent constitutional units. polypropylene polypropylene (pŏl'ēprō`pəlēn), plastic noted for its light weight, being less dense than water; it is a polymer of propylene. It resists moisture, oils, and solvents. homopolymer into olefinic elastomers. The rubber component of the composition is cured. |
