Poly(2,4-dimethylstyrene)
polymerPoly(2,4-dimethylstyrene) is a substituted polystyrene—an aromatic vinyl polymer with methyl groups at the 2 and 4 positions of the benzene ring. This is primarily a research and specialty polymer rather than a commodity material, developed to explore how structural modifications to polystyrene affect thermal stability and mechanical properties. The dimethyl substitution pattern increases molecular rigidity and thermal resistance compared to unsubstituted polystyrene, making it of interest for applications requiring elevated-temperature performance or improved dimensional stability where conventional polystyrene falls short.

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.
