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.
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.
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 ...
The bonding temperature is lower than with most other HMAs, only about 50 °C (122 °F) to 70 °C (158 °F), when the adhesive behaves as a soft rubber acting as a pressure-sensitive adhesive. The surface wetting in this amorphous state is good, and on cooling the polymer crystallizes, forming a strong flexible bond with high cohesion.
Acrylate and methacrylate homo- and copolymers are made by radical polymerization in toluene-acetone for coating applications. Polyethylene (HDPE, LLDPE) - some grades are made by coordination polymerization in high boiling hydrocarbone solvents (above PE solution temperature). The advantage of this process is very high propagation rate ...
PAA, like any acrylate polymer, is usually synthesized through a process known as free radical polymerization, [3] [4] though graft polymerization may also be used. [5] [6] Free radical polymerization involves the conversion of monomers, in this case, acrylic acid (CH 2 =CHCO 2 H), into a polymer chain through the action of free radicals.
Another method tested in a study to produce sodium polyacrylate as an alternative to current methods began with Butyl acrylate-acrylic acid copolymer and poly (butyl acrylate). [4] They were synthesized via suspension polymerization by using butyl acrylate as the main monomer and acrylic acid as a secondary monomer. Suspension polymerization ...
