V-Pyrol™/RC reactive monomer

V-Pyrol/RC reactive monomer is a clear liquid stabilized with insoluble sodium hydroxide or soluble N,N’-di-sec-butyl-p-phenylenediamine. The latter inhibitor is supplied in V-Pyrol/RC reactive monomer and V-Pyrol/Amine at concentrations of 25ppm and at 100 ppm, respectively for radiation curing and nonradiation curing applications. V-Pyrol/RC reactive monomer is commonly used in radiation cured forumulations. 

This monomer is known to be a supercooled liquid well below its freezing point of 13°C. It can remain as a liquid at room temperature for extended periods. Rapid, exothermic crystallization under these conditions should not be confused with bulk polymerization.

V-Pyrol/RC reactive monomer accelerates UV curing rates as the reactive diluent. Typically formulated with an acrylate oligomer, it imparts unique solution viscosity reduction and enhanced adhesion to non-polar substrates. The activated double bond of V-Pyrol facilitates its use in free radical homo- and copolymerizations and grafting reactions. The products of these reactions are either linear or crosslinked homopolymers and nonionic, anionic and cationic copolymers. 

Polymers from V-Pyrol are amorphous and the pyrrolidone ring imparts hydrophilicity, adhesiveness, strength and complexing capability.
