Polymerizable and polymeric surfactants in emulsion polymerization for water-borne coatings

Objective



After the "human capital and mobility" network chrx 93 0159, on about the same subject, just ended on Dec 31 1996, a selection of reactive surfactants suitable for emulsion polymerization (based on maleic reactive groups) has been done. Then surfactants lead to latexes with better stability and film with improved performances. The present project, with the same coordinator, has a double purpose: 1. Scale up the production of these selected surfactants, and also the production of film forming latexes. in amount large enough for them to be formulated and tested in end-use of water borne paints, adhesives, paper coatings, printing inks and textile coatings. This work will be done chiefly by industrial partners specialised in the concerned domains. 9. Continue the basic studies in the field, to confirm the potential interest of some other surfactants already prepared by the Network, and develop entirely new surfactants and new methods to produce them, as weil as poiymeric surfactants. These basic studies will be carried out chiefly by the participants of the previous Network who are willing to continue to cooperate and also by a laboratory from the University of RIGA in Latvia, working on maleate derivatives. These new surfactants will, hopefully, might be selected in further steps of the program for scaling up processes and testing in end-uses, on very severe criteria. 3. Explore the capability and possible benefits in new related heterogeneous processes such as microemulsion and miniemulsion and also the very new system of controlled radical polymerization ;; which, up to now have never been applied sucessfully to emulsion polymerization being limited to solution polymerization. The surfactants will be chiefly SURFMERS (possibly TRANSURFS or INISURFS), anionic or non-ionic with polymerizable groups such as maleic (possibly acrylic or styrenic), hydrophilic sequences of polyethylene oxide, and hydrophobic sequences of either hydrocarbons or polyoxiranes (propyl, butyl). Some polymeric surfactants, prepared independantly out side of the emulsion process will be also tested. Scaling up of surfactants will be carried out by A KC ROS . The film forming copolymers to be studied will be mainly acrylics such as Styrene-Butyl-Acrylate-Acrilic acid or Styrene-Butadiene Acrylic acid, to be prepared by AKZO Resin, and Vinylic copolymer such as Vinylacetate VEOVA, or Vinylacetate-ethylene, to be prepared by VINAMUL. The application will be paints and printing inks (AKZO Coatings), paper coatings (SCA GRAPHICS), adhesives and textile coatings and other possible application(VINAMUL). In total, eleven partners, among then 6 basic research laboratories with 6 thesis (or post doc) students to be trained and 5 Industrial partners
