Polymers are both man-made and naturally occurring. Rubber, for example, is a natural polymeric material that has been used for thousands of years. It has excellent elastic qualities, the result of a molecular polymer chain created by mother nature. Another natural polymer is shellac, a resin ...
Learn what Polymethyl methacrylate (PMMA) is and how this biocompatible material can be used in eye, bone and dental surgery.
These can be fabricated, for example, by depositing a synthetic polymer, such as PMMA, onto a gold nanosurface using electron beam lithography. Gradient index plasmonic metamaterials were used to fabricate Luneburg and Eaton lenses that interact with surface plasmon polaritons instead of conventional ...
Poly(acrylic acid) or PAA (CAS number 9003-1-04) is a type of polymer. The monomer of poly(acrylic acid) is Acrylic Acid. In a water solution at neutral pH, many of the side chains of PAA will lose their protons and acquire a negative charge. For a description of unrelated compounds...

“Polymeris a chain-like molecule consisting of repeating subunits, forming long and larger molecules.” Noun ▲ A material consisting of polymer molecules “The scientist synthesized a newpolymerwith enhanced durability and flexibility.” Adjective ...
PMMA (acrylic resin), PC (polycarbonate), COC (cyclo-olefin copolymer) and COP (cyclo-olefin polymer), and some plastic materials are used for plastic lenses.
The synthetic polymer of methyl methacrylate, PMMA was developed simultaneously by multiple laboratories and chemists in 1928 and was first brought to market in 1933 under the trademark Plexiglas. PMMA was used extensively as safety glass throughout World War II, during and after which it was rapid...
Acrylic is polymethyl methacrylate (polymethyl methacrylate), referred to as PMMA, which is a kind of polymer formed by polymerization of methyl methacrylate, also known as organic glass, with high transparency, high weather resistance, high hardness, ad
What is PMMA used for? PMMA is commonly used in applications that require clarity, such as optical lenses, signs, and displays. What is LLDPE used for? LLDPE is commonly used in applications that require flexibility and stretchability, such as packaging films, stretch wraps, and agricultural fil...
