Monomers such as hydrophobic olefinically unsaturated monomers have been grafted onto maltodextrins and other low molecular weight starch hydrolyzates to prepare stable fluid emulsions of coatable viscosity and reduced graininess. Polymer films of high tensile strength which are useful in a variety of applications, including high temperature applications may be formed by casting and drying these emulsions.

Starch polymer graft composition and method of preparation

A binder for non-woven fibers or fabrics is prepared comprising a starch-polymer graft, starch and a starch crosslinking agent. An acrylamide copolymer may optionally be included. The binder is useful for non-woven fibers such as a polyester fiber mat, and particularly single ply, bitumin roofing materials.
