Up-to-date coverage of methods of emulsion polymerization
This book provides a comprehensive reference on emulsionpolymerization methods,focusing on the fundamental mechanisms andkinetics of each process, as well as howthey can be applied to themanufacture of environmentally friendly polymeric materials.
Topics covered include:
* Conventional emulsion polymerization
* Miniemulsion polymerization
* Microemulsion polymerization
* Industrial emulsion polymerization processes (primarily thesemibatch and continuous reactions systems)
* The role of various colloidal phenomena in emulsionpolymerization
* Important end-use properties of emulsion polymer (latex)products
* Information on industrial applications in paints, coatings,adhesives, paper and board, and more
This is a hands-on reference for graduate students andprofessionals in polymerchemistry, chemical engineering, andmaterials science who are involved in researchon coatings,adhesives, rubber, latex, paints, finishes, and other materialsthat can becreated using various methods of emulsionpolymerization.
