Propylene/1-pentene random copolymers are a relatively new family of random copolymers being prepared by Sasol Polymers and reveals high impact strength, good tensile properties, excellent optical properties, good rheological ...

Xanthate-mediated polymerization was investigated as a tool for the preparation of well-defined poly(N-vinylpyrrolidone) and copolymers of N-vinylpyrrolidone. Some results regarding the monomer vinyl acetate are included, ...

ENGLISH ABSTRACT: Density functional theory (DFT) has been used to investigate the effect of the surrounding molecules on the structure of selected boron-nitrogen compounds. It was found that a very limited number of ...

Aqueous polyurethane (PU) dispersions were synthesized for use in paper coatings. These PUs contained a polyester polyol soft segment (content of between 65 to 75%) and a urethane hard segment (content of between 30 to ...

The work presented in this dissertation describes the development of self-healing coatings based on thiol-ene chemistry. The approach was to synthesize capsules with thiol and ene compounds separately encapsulated. These ...

ENGLISH ABSTRACT: To comply with the ever growing demands for materials with better properties and complex architectures, polymer chemistry has resorted to the use of living free radical polymerization techniques. Despite ...

Polypropylene is an extremely versatile material and has a broad spectrum of applications due to the variations in properties which are possible with this material. The variations in the properties of the material are ...

This study involves the synthesis and characterisation of PEG-based amphiphilic block copolymers for the hydrophilization of polysulphone ultrafiltration membranes. PEG based macro RAFT agents were synthesized and ...

The research presented in this dissertation was concerned with the living radical polymerization (LRP) of an amphiphilic, water-soluble, bi-substituted and biologically compatible acrylamide derivative, namely ...

The study described in this dissertation examines the synthesis of mainly acrylate-based surfactants and their subsequent use as emulsifiers/stabilisers in the emulsion polymerisation of styrene. Some acrylamide-based ...
