Poly(octadecyl methacrylate)

polymer

Poly(octadecyl methacrylate) is a long-chain alkyl methacrylate polymer synthesized by polymerizing octadecyl methacrylate monomers, yielding a material with extended hydrocarbon side chains that impart hydrophobic and low-temperature properties. This polymer is primarily of research and specialized industrial interest rather than a commodity material, used in applications requiring low-temperature flexibility, water resistance, and tailored surface properties such as coatings, adhesives, and smart polymer systems. The long alkyl side chains distinguish it from shorter-chain methacrylates, enabling unique combinations of processability and environmental durability that make it valuable for niche applications in advanced polymeric formulations.

Safety & Biocompatibility

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.
