Poly(methyl methacrylate)
Product Information
Molecular Formula
(C5H8O2)x
Description
Methyl methacrylate monomer appears as a clear colorless liquid. Slightly soluble in water and floats on water. Vapors heavier than air. Vapors irritate the eyes and respiratory system. Containers must be heavily insulated or shipped under refrigeration. An inhibitor such as hydroquinone, hydroquinone methyl ester and dimethyl t-butylphenol is added to keep the chemical from initiating polymerization. The chemical may polymerize exothermically if heated or contaminated with strong acid or base. If the polymerization takes place inside a container, the container may rupture violently. Used to make plastics.

| Molecular Weight | Description |
|---|---|
| average Mw ~120,000 by GPC | May contain < 2% toluene. Refractive index is n20.D 1.49. |
| average Mw ~350,000 by GPC | PMMA (avg. Mol wt. ~350,000 g mol-1) containing Fe2O3 and TiO2 fillers have possible uses as flame retardants. |
| average Mw ~15,000 by GPC | It finds uses in biological applications because of its lower water absorption capability and biocompatibility. |
