Pentaerythritol tetraacrylate
The chemical Pentaerythritol tetraacrylate is an organic compound. It is a tetrafunctional acrylate ester monomer used primarily in the manufacture of polymers. It has the CAS Registry Number 4986-89-4.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
One of the key uses of the material is in polymeric synthesis where it can form micelles and block copolymers.
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. It is available ethoxylated where it also finds use in electron beam curing. The material also has pharmaceutical uses
