https://doi.org/10.1007/978-3-7091-6924-7The reaction of a solution of a OH-groups-containing polymer with a diisocyanate or a dicarboxylic acid dichloride leads to a gel, crosslinked by covalent bonds. The crosslink density depends at a given polymer concentration on the concentration of OH-groups in the polymer chains and on the conversion of the reaction.

Bernhard Frevel,Michaela WendekammRecently a two parameter dilute solution theory of homopolymers was successfully applied. to statistical copolymer-solvent and block polymer-solvent systems. The following basic assumptions were made:

Ionomer Graft Copolymers of Polystyrene-Polybutylacrylate,Nearly all systems of two or more different polymers are incompatible, meaning that solutions of the two polymers above a certain concentration as well as the polymers them-selves are not mixible together in the sense of a molecular dispersed mixture. This also applies to blends of polystyrene and polybutylacrylate.

Morphology and Deformation Behavior of Crosslinked Butylacrylate Copolymer Gels, Prepared by Graft The reaction of a solution of a OH-groups-containing polymer with a diisocyanate or a dicarboxylic acid dichloride leads to a gel, crosslinked by covalent bonds. The crosslink density depends at a given polymer concentration on the concentration of OH-groups in the polymer chains and on the conversion of the reaction.
