Acrylic resin, a group of related thermoplastic or thermosetting plastic substances; Acrylic fiber, a synthetic fiber of polyacrylonitrile; Acrylic paint, fast-drying paint containing pigment suspension in acrylic polymer emulsion; Poly(methyl methacrylate), also known as acrylic glass or Plexiglass, a transparent thermoplastic
It has a density of 1.17–1.20 g/cm 3, [1] [16] which is approximately half that of glass, which is generally, depending on composition, 2.2–2.53 g/cm 3. [1] It also has good impact strength, higher than both glass and polystyrene, but significantly lower than polycarbonate and some engineered polymers.
An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high ...
Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C. It is used primarily for producing oil seals and packaging related ...
Methacrylates ( CH 2 =C(CH 3)CO 2 R) and cyanoacrylates ( CH 2 =C(CN)CO 2 R,) are closely related to acrylates. The feature a methyl and a nitrile in place of the H alpha to the carboxy functional group. They share several properties, being polymerized by radicals and being colorless. [2] Structures of some important modified acrylates
Acrylic acid (IUPAC: prop-2-enoic acid) is an organic compound with the formula CH 2 =CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform ...
Plastic is the generic name for a family of synthetic materials derived from petrochemicals. It is often product of two or more components. It is often product of two or more components. There are many families of plastics and polymers being used in construction industry, such as acrylics , composites , expanded polystyrene , polycarbonates ...
2 CH 3 −CH=CH 2 + 2 NH 3 + 3 O 2 → 2 CH 2 =CH−C≡N + 6 H 2 O. In the SOHIO process, propylene, ammonia, and air (oxidizer) are passed through a fluidized bed reactor containing the catalyst at 400–510 °C and 50–200 kPa g. The reactants pass through the reactor only once, before being quenched in aqueous sulfuric acid.
