Abstract
The invention relates to polymers, which are produced through using organic acids, together with the products obtained therefrom. The polymers and the products obtained therefrom are insoluble in water, but soluble in an alkaline medium. There are numerous interesting possible uses for the polymers.
Claims7
An extruded water insoluble, basic medium soluble, thermoplastic polymer prepared from a monomer mixture comprising from about 2.5 to about 6 mol of at least one of methylacrylate and ethylacrylate per mol of at least one of acrylic acid and methacrylic acid, and a termonomer selected from the group consisting of a vinyl ether having 3 to 18 carbon atoms and a vinyl hydrocarbon having 8 to 11 carbon atoms, the acid mol ratio to termonomer mol ratio being 1:0.1 to 1:0.4, said polymer having a carboxylic group content of between about 5 and 15%.
