Emulsion Polymerisation | Lankem Surfactants |

Emulsion Polymerisation

Emulsion Polymerisation is a method in which polymers are prepared. The process of emulsion polymerisation consists essentially of forming an emulsion of a monomer, or a mixture of co-monomers, in an aqueous medium by the use of emulsifiers and then to polymerise the system in a controlled way with the use of an initiator.


The selection of suitable emulsifiers is complex and in some cases, anionics or nonionics can be used singularly but in most cases, an anionic/nonionic system is preferred as a way of increasing the stabilisation of the latex.


After many years of practical experience, we can provide starting surfactant recommendations for each polymer type listed. In most cases, the polymer chemist will need to evaluate the emulsifiers types, additional levels and ratios in order to obtain the required performance.

Polyvinyl acetate homopolymer emulsions, often called PVAc or occasionally PVA homopolymers. Polyvinyl acetate is synthesized by the emulsion polymerisation of vinyl acetate monomer (VAM). PVAc emulsions are best known for their use in wood glues or school glues due to their strong adhesion properties. However, PVAc emulsions are also widely used in many industrial and consumer end-use applications:

  • Water-based adhesives

  • Carpet backings

  • Paper and paperboard coatings

  • Carpet backings

  • Building and construction products
