However, as with cold sores and shingles, Valtrex is not a cure for genital herpes. Valtrex was approved for treating chickenpox in children based on studies of acyclovir (ZoviraxÂ®), a very similar medication. Other studies have shown that Valtrex (which the body transforms into acyclovir) is safe in children.
Polyvinyl alcohol. Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH2CH(OH)]n. It is used in papermaking, textiles, and a variety of coatings. It is white (colourless) and odorless. It is sometimes supplied as beads or as solutions in water.
Polyvinyl acetate (PVA or PVAc) is a thermoplastic polymer with a chemical formula of (C4H6O2)n. It is normally manufactured by the free radical polymerization of vinyl acetate. The procedure involves the reaction of monomer molecules of vinyl acetate by submerging them into water.
