*  Effect of polymeric cement additives on the mobility of radionuclides under near-field conditions of a final radwaste...
As part of this project, the work packages performed by our group are focused on the mobilising potential of polymeric additives contained in cement; so-called superplasticisers, which may be set free by leaching. Their complexing properties could keep radiometals in solution, facilitating their migration. For the example of polycarboxylate ethers as new generation of superplasticisers, conditions of a mobilisation will be identified in systematic investigations of complexation and adsorption in dependence on pH and electrolyte content. The effects of these parameters shall be explained by modelling on the basis of interactions in the constituent subsystems. Taking advantage of the unique analytical benefits of radioactive tracers is the central idea of our experimental work. 14C-labelled polycarboxylate ethers will be synthesised, providing access to very low concentration levels. 152Eu is employed as a tracer analogue of actinides.. ...

*  Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications
The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. As the end-group functionality was identical in all polymers, the differences observed in DNA binding and in vitro transfection studies were directly related to the length of the hydrophobic poly(trimethylene carbonate) backbone and the number of functional end-groups. This enabled the use of this polymer system to explore the effects of structural elements on the gene delivery ability of cationic polymers, revealing striking differences between different materials, related to functionality and cationic charge density.. In an effort to achieve more flexibility in the synthesis of functional polymers, polycarbonates were synthesized in which the functionalities were distributed along the polymer backbone. ...

Weatherable polycarbonate compositions (formulations or blends) comprise polycarbonate, cycloaliphatic polyester resins, at least one of a benzotriazole, benzophenone, and triazine based UVA, and a catalyst quencher. The incorporation of the cycloaliphatic polyester resin and the benzotriazole, benzophenone, and triazine based UVA exhibits a synergistic effect, thereby resulting in unexpected enhanced protection of the polycarbonate compositions by imparting photostability to the polycarbonate formulations, thereby reducing yellowing or other forms of light induced degradation.
*  Patent US6583233 - Method for preparing polyether copolymers with polycarbonates and polyarylates - Google Patents
Copolymers of polycarbonates or polyarylates with polyether polymers such as polyethersulfones, polyetherketones, and polyetherimides are prepared by reaction of the polyether polymer-forming reagents, e.g., bisphenol A disodium salt and bis(4-chlorophenyl) sulfone, in the presence of the polycarbonate or polyarylate. The reaction may take place in a dipolar aprotic solvent, or in a water-immiscible aromatic solvent in the presence of a phase transfer catalyst, preferably a hexaalkylguanidinium halide. Hydroxy-terminated polyether oligomers may be produced from the copolymers by saponification of carbonate or ester groups.

*  Plus it
Polycarboxylate superplasticizer (PCE) is a widely used water-reducing agent that can reduce significantly the water demand of concrete, which reduces the porosity and enhances the strength and durability of the concrete. (The PCE consists of a single backbone with many long PEO side chains.) Generally, aggregate occupies ,70 wt.% of concrete; clay minerals are ubiquitous in nature and are difficult to avoid in mined aggregates. Clay minerals in aggregate often render the PCE ineffective and give rise to rapid loss of the fluidity of the concrete; this phenomenon is referred to as 'poor clay tolerance of PCE.' Though the poor clay tolerance of PCE is known widely, the relationship between the clay tolerance and the molecular structure of the PCE, in particular the effect of the side-chain structures, on clay tolerance is not understood completely. The objective of the present study was to determine the effect of different grafting densities of polyethylene oxide (PEO) side ...

Processes are described for making highly absorbent tissues and towels by wet-laying pulps comprising particular polycarboxylate polymer-modified fibrous pulps such as mildly hydrolyzed methyl acrylate-grafted softwood kraft pulps; these pulps have distinct protonated and alkali-metal-cation-exchanged states. The wet-laying processes are adapted to exploit the very different behavior of the polymer-modified fibrous pulps in function of the two states. The preferred wet-laying processes described herein are continuous processes embodying one or more on-line chemical treatment steps which chemically switch state of the polymer-modified fibrous pulp component in a wet web on the papermaking machine to improve the processing thereof by averting or minimizing tendencies to mechanically or thermally degrade.
