Poly methyl methacrylate can be resistant to dilute inorganic acids, but the concentration of inorganic acids can make it eroded, alkali-resistant, but the warm sodium hydroxide, potassium hydroxide can make it etch, salt-resistant And aliphatic, aliphatic hydrocarbons, insoluble in water, methanol, glycerol, etc., but can absorb alcohol swelling, and stress cracking, intolerance ketones, chlorinated hydrocarbons and aromatics. Its solubility parameter is about 18.8 (J / CM3) 1/2, in many chlorinated hydrocarbons and aromatic hydrocarbons can be dissolved, such as dichloroethane, trichlorethylene, chloroform, toluene, etc., vinyl acetate and acetone can also make it Dissolved.

Poly methyl methacrylate(acrylic, perspex) has good resistance to ozone and sulfur dioxide and other gases.
