Product Description of POLY(METHYL METHACRYLATE) ISOTACTIC CAS#25188-98-1
Poly(methyl methacrylate) (PMMA), widely recognized as acrylic or plexiglass, is a high-molecular-weight thermoplastic polymer with the repeating unit (C₅H₈O₂)ₙ. It is highly regarded for its exceptional optical clarity, competitive cost, and ease of fabrication.
PMMA is synthesized via the polymerization of methyl methacrylate (MMA) monomers, where the carbon–carbon double bonds undergo chain-growth reaction initiated by a suitable initiator, forming extended polymer chains. The production process is well-established and efficient, and by varying the synthesis conditions, both the molecular weight and polymer architecture can be precisely tuned to meet the diverse performance demands of different end-use applications.
