A water soluble, substantially linear, polymer ismade by copolymerisation of a water soluble blend ofmonoethylenically unsaturated monomers comprisingcarboxylic acid monomers such as acrylic acid and ahydroxylic monomer of the formula CHR1=CR2-Y-M a-OH where R1 is hydrogen or carboxy, R2 is hydrogen, carboxy ormethyl, Y is O, CH2O or COO, M is alkyleneoxy and a is atleast 5. This polymer can be cross linked, generallyafter being shaped by extrusion or other shaping of anaqueous solution of the polymer, to form cross linkagesbetween the carboxyl and hydroxyl groups. The shapedelements can have high eater absorbency and can be in theform of, for instance, fibres or films.
