Descripción

Isoprene is used in to prepare synthetic version of natural rubber by polymerization using Ziegler catalysts. It is a basic building block for terpenes especially carotenes, terpenoids, retinol, vitamin-A and tocopherol (Vitamin-E). It finds applications in medical equipments, toys, baby bottle nipples, shoe soles, elastic films and threads for golf balls. Copolymer prepares in association with styrene is used in pressure sensitive adhesives.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El isopreno se utiliza en la preparación de la versión sintética de caucho natural mediante polimerización utilizando catalizadores de Ziegler. Es un compuesto básico para los terpenos, especialmente los carotenos, los terpenoides, el retinol, la vitamina A y el tocoferol (vitamina E). Se aplica en equipos médicos, juguetes, tetinas para biberones, suelas de zapatos, películas elásticas e hilos para pelotas de golf. El copolímero se prepara junto con estireno que se utiliza en adhesivos sensibles a la presión.

Solubilidad
Miscible con etanol, éter etílico, alcohol, acetona y benceno. No miscible con agua.

Notas
Almacenar en un lugar fresco. Incompatible con agentes oxidantes, bases fuertes, amoniaco, metales alcalinos, alcoholes y oxígeno.
