Butyl acrylate is of low acute toxicity with an LD 50 (rat) of 3143 mg/kg. [4]In rodent models, butyl acrylate is metabolized by carboxylesterase or reactions with glutathione; this detoxification produces acrylic acid, butanol, and mercapturic acid waste, which are excreted.
Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate is significantly less volatile than simpler phenolic antioxidants such as butylhydroxytoluene (BHT). This makes it more suitable to stabilising plastics, as it is not driven out by the high temperatures experienced during plastic extrusion and moulding, [2] when they are heated to 150-320 °C (300–600 °F).

tert-Butyl methacrylate is an organic compound with the formula (CH 3) 3 CO 2 CC(CH 3)=CH 2. A colorless solid, it is a common monomer for the preparation of meth acrylate polymers . [ 2 ] It is employed in other kinds of polymerizations .
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
Poly(butyl acrylate) (PBA) is a family of organic polymers with the formula (CH 2 CHCO 2 CH 2 CH 2 CH 2 CH 3) n. It is a synthetic acrylate polymer derived from butyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers.
In the 1960s, James A. Herbig and Ival O. Salyer of Monsanto were the first to attempt to make what would become ASA using butyl acrylate as the rubber phase. This work was then refined by Hans-Werner Otto and Hans Peter Siebel of BASF using a copolymer of butyl acrylate with butadiene for the rubber phase. [10]
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
The acrylate ion is the anion CH 2 =CHCO − 2. Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate. These acrylates contain vinyl groups. These compounds are of interest because they are bifunctional: the vinyl group is susceptible to polymerization and the carboxylate group carries myriad ...
