Poly(3-methylstyrene)

polymer

Poly(3-methylstyrene) is a thermoplastic aromatic polymer derived from 3-methylstyrene monomers, representing a substituted polystyrene variant with a methyl group at the meta position on the phenyl ring. This material is primarily encountered in research and specialty applications rather than high-volume industrial production, where the methyl substitution can modulate mechanical properties and thermal behavior compared to conventional polystyrene. Engineering interest in this polymer centers on fine-tuning performance for applications requiring tailored stiffness or processing characteristics, though it competes with more established styrenic copolymers and engineering plastics in most commercial sectors.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
