polymerization processes of pva emulsions

Encapsulation technologies A general overview

• Encapsulation defines no size notion • Microencapsulation usually refers to sizes ranging from 1 µm to 1 mm • Nanoencapsulation is used for nanometric sizes but sometimes refers to sizes ranging up to 1 µm or few micrometers The current presentation focuses on sizes ranging from 1 µm to few millimeters.

Properties of Polyvinylester

PVAC emulsions are rather inexpensive and possess good adhesion to many porous substrates, such as wood and paper. PVAC is not the only vinyl ester. Other vinyl esters have been synthesized, either by direct polymerization or by ester interchange between polyvinyl acetate and other esters/acids.
