1. Association Phenomena Involving Hydrophobically Modified Polymers. Electrostatic and Hydrophobic Contributions
Abstract : The electrostatic and hydrophobic interactions in aqueous solutions of hydrophobically-modified water-soluble non-ionic or ionic polymers, their mixtures with a second polymer, nonionic or of opposite charge, and their mixtures with surfactants of opposite charge have been investigated. The relative strength of the electrostatic and hydrophobic contributions has been modulated by a variation of the polymer charge density and the solution pH, and by a variation in the degree and strength of the hydrophobic modifications, respectively.

2. Molecular Association Studied by NMR Spectroscopy
Abstract : This Thesis presents studies of molecular association in aqueous solution and at the liquid/solid interface. The investigated molecular systems range from self-aggregating surfactants to hydration water in contact with micelles or individual molecules. In most studies, combinations of various NMR methods were applied. READ MORE

3. Protein-Polymer Interaction and Association in Aqueous Solution
Abstract : The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. READ MORE

4. Solution properties of a hydrophobically modified polymer
Abstract : The influence of hydrophobic modification on solution properties of water-soluble polymers in the semi-dilute regime have been studied. The nonionic ethyl(hydroxyethyl)cellulose (EHEC) and its hydrophobically modified analogue (HM-EHEC) are used as model substances. READ MORE

5. Molecular associations and transport properties of amphiphiles and gastrointestinal mucin in aqueous solution
Abstract : An effective uptake/absorption of drug formulations involve many processes; one being the transport of the active molecule through the mucus layer. The mucus layer is a complex mixture of biological molecules. Among them, mucin is the molecule that mainly provides the gel properties of the layer. READ MORE
