Polymers
Poly(methyl methacrylate) (PMMA) Standards
The PMMA Standards collection comprises high-purity poly(methyl methacrylate) reference materials with tightly controlled molecular weights and distributions. These standards are designed for gel permeation/size-exclusion chromatography (GPC/SEC) calibration, ensuring accurate molecular weight determination of polymers. Polysciences offers PMMA standards such as MW ~185,000 with Mw/Mn ~1.10, as well as other grades.
