Pentaerythritol tetraacrylate (PETA or sometimes PETRA) is an organic compound. It is a tetrafunctional acrylate ester used as a monomer in the manufacture of polymers.[1]
Uses
PETA is part of a family of acrylates used in epoxy resin chemistry and Ultraviolet cure of coatings. Similar monomers used are 1,6-Hexanediol diacrylate and TMPTA trimethylol propane triacrylate. It is a derivative of pentaerythritol[2] One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers[3]. As the molecule has 4 acrylate groups that functionality enables the molecule to do the Michael reaction with amines. It is therefore sometimes use in epoxy chemistry enabling a large reduction in cure time[4]. It is available ethoxylated where it also finds use in electron beam curing[5]. The material also has pharmaceutical uses[6]
