Description

2,4-Diphenyl-4-methyl-1-pentene (CAS 6362-80-7 ) is a specialty monomer and polymerization modifier used in the rubber and polymer industries. It functions as a chain transfer agent and initiator modifier during synthesis. This chemical influences molecular weight distribution and polymer architecture. In rubber compounding and synthetic elastomer production, it is used to control chain length during polymerization processes. This control directly affects the mechanical performance of the final compound. Tire manufacturers and rubber goods producers rely on precise molecular weight control to meet specific tensile and elasticity targets. This compound is highly relevant at the formulation stage for various industrial applications. In plastics and polymer processing, it supports the synthesis of defined oligomeric or polymeric structures. It is essential where branching and end-group composition must be tightly managed. It also serves as a building block in specialty polymer research where controlled radical or ionic polymerization techniques are used. These techniques demand well-characterized transfer agents for successful outcomes. The product is supplied as a liquid in standard commercial quantities, ranging from laboratory-scale packaging to bulk industrial volumes. It is available in technical grade, with purity specifications commonly at 97% or higher depending on the supplier. Buyers sourcing for research should confirm purity and inhibitor content prior to use. Contact us for supply of 2,4-Diphenyl-4-methyl-1-pentene Request Quote
