Assumptions for Synthesis of Hybrid Dispersions

Based on the literature survey (see Section 6.2) and the anthor s preliminary experiments the following methods of synthesis of hybrid dispersions (after this point in the chapter they will be called modified DPUR (MDPUR)) were selected  

2) using the monomers as active diluents (co-solvents) of prepolymer-ionomer followed by their polymerisation after emulsifying the prepolymer-ionomer in water 

3) emulsifying the prepolymer-ionomer in diluted acrylic-styrene dispersion (ASD) 

Hybrid dispersions obtained by polymerisation, i.e., according to methods la, lb and 2, will be designated as MDPUR-ASD and hybrid dispersions obtained by synthesis of PUR in ASD, i.e., according to method 3, will be designated as MDPUR. 

NCO - terminated prepolymer-ionomer diluted with NMP or acetone
