Dispersion of vinylacetate copolymer with dibutyl maleinate
It is a product of emulsion polymerization of vinylacetate with dibutyl maleinate in presence of protective colloid or surfactant.
Like dispersion with ethylene (CDVE) forms elastic films on drying without any plasticizer.
Coarse dispersion grades are used for preparation of aqueous emulsion paints, as a glue in printing trade, for sticking together unvowen reinforcing materials, in compounds for coatings of hard cheese.
Fine dispersion grades are used for production of thermoplastic materials for making inner elements of shoes, paper of executive quality, and aqueous emulsion paints.
