Abstract: The present invention provides a polymer comprising units according to formula III wherein R1 is selected from C1 to C10 alkylene and C5 to C20 arylene; each R2 is selected independently from H and C1 to C10 alkyl; and R3 and R4 are selected independently from H and C1 to C30 alkyl. Embodiments of the invention provide polymers that are water soluble or water swellable and can form transparent and flexible films.

Abstract: The present invention relates to modifiable linear polyunsaturated polymers and processes for preparing the same comprising reacting solely at least one bifunctional nucleophilic compound with at least one ?-functional unsaturated monomer. The at least one bifunctional nucleophilic compound of the invention comprises two nucleophiles independently selected from the group consisting of C, N, O, S and Se. The at least one ?-functional unsaturated monomer of the invention comprises two leaving groups L1 and L2, wherein at least one of the leaving groups L1 and L2 of the at least one ?-functional unsaturated monomer is part of the nonaromatic unsaturated structure C?C—C?-L. The double bond of said ?-functional unsaturated monomer is maintained in the polyunsaturated polymer.

Abstract: Disclosed are processes for preparing modifiable poly(aralkyl ketone)s having active methylene group(s) in the main chain comprising reacting an aralkanoic acid or mixtures thereof in the presence of one alkane or aryl sulfonic acid and a condensing agent. Also disclosed are novel modifiable poly(aralkyl ketone)s obtainable by the processes of the inventions.
