Poly(methyl methacrylate) or PMMA is commonly reffered to as acrylic or acrylic glass. So generally, they're the same thing.
What are hard contact lenses made of?
Hard contact lenses are made of a plastic polymer called polymethyl methacrylate.
Does plastic have brittleness?
Plastics can be designed to be very brittle or very tough and flexible. Polymethyl methacrylate is quite brittle for example.
Why is PMMA (polymethyl methacrylate) not soluble in ethanol but is soluble in 2-butanone?
because 2-butanone is a mixture so ethanol and water do not but mixtures do.
What is the chemical formula for acrylic?
The Chemical Name For Acrylic Is:"Polymethyl-Methacrylate" And Is Commonly Known As PMMA.The Chemical Symbol/Formula Is:(C5O2H8)n
Is crystalite asbestos?

Where is acrylic obtained from?
You first produce methacrylic acid. Once you're there, you esterify it to methyl methacrylate monomer. Polymerizing the monomer produces polymethyl methacrylate, which is the chemical name of acrylic plastic. Over 8 billion kilograms of acrylic were sold in 2015, so there are a lot of companies making it and quite a few different processes.
What are contacts made out of?
These are the types of contact lenses and the material(s) they're made out of: 1. rigid lenses - polymethyl methacrylate (now improved) 2. soft lenses - silicon hydrogel (which is the material that is being used in manufacture of contact lenses today) 3. hybrid - mixture of materials of both rigid and soft lenses
