2-Hydroxyethyl Acrylate is a functional acrylate monomer containing both vinyl and hydroxyl groups, enabling participation in free-radical polymerization while introducing polar functionality into polymer backbones. Commonly referenced as 2-hydroxyethyl acrylate, HEA, and hydroxyethyl acrylate, this compound (CAS 818-61-1) is typically used in polymer synthesis, where the hydroxyl group allows post‑reaction modification and intermolecular interaction within resin and copolymer systems. In industrial supply contexts, it is provided with competitive factory pricing, supports customized specifications, and is supplied with complete documentation including MSDS, TDS, COA, suitable for bulk supply.

FAQ - Technical & Supply Chain
-
Q:
Are p-Phenylenediamine and 1,4-Benzenediamine considered the same chemical entity?
A: Yes, both terms describe the identical aromatic diamine compound registered under CAS 106-50-3, distinguished by the para-substitution of two amino groups on the benzene ring. -
Q:
Is this intermediate suitable for synthesizing aramid polymers?
A: p-Phenylenediamine is widely applied as a fundamental monomer in the condensation reaction with terephthaloyl chloride to produce poly-paraphenylene terephthalamide, known commercially as aramid fibers.View source details for citation from Åbo Akademi. Opens side panel.
