Polyvinyl Acetate an overview ScienceDirect Topics

A. Emblem in Packaging Technology 2012 Polyvinyl acetate and polyvinyl alcohol. Polyvinyl acetate (PVA) and polyvinyl alcohol (PVOH) are further examples of ethylene copolymers. PVA is used as an emulsion adhesive for bag sack and carton making. PVOH is produced by hydrolysis of PVA and the strong hydrogen bonding imparted by the OH groups means that pure PVOH is water soluble.

Emulsion polymerization Wikipedia

Advantages of emulsion polymerization include High molecular weight polymers can be made at fast polymerization rates. By contrast in bulk and solution freeradical polymerization there is a tradeoff between molecular weight and polymerization rate. The continuous water phase is an excellent conductor of heat enabling fast polymerization rates without loss of temperature control.
