Polyurethane adhesives, sealants, coatings and? The main applications of polyurethanes are presented in Figure 1.
The continuous phase is the polyurethane polymer and the discontinuous phase is the gas phase. Polyurethanes are an extremely versatile group of polymers, produced in a wide range of densities, crosslink densities and stiffnesses, from very soft to very hard structures, as shown in Figure 1.
Considering the practical and applicative reasons, the polyurethanes can be divided into two main categories: elastic polyurethanes, e. This common classi? A diisocyanate reacted with a high MW diol for example polyether or polyester diol of MW of leads to very elastic linear polyurethanes polyurethane elastomers [3, 6, 13, 14, 24, 25].
This structure is in fact an interesting, virtually crosslinked structure by secondary bonds hydrogen bonds. At higher temperatures, the hydrogen bonds are destroyed and it is 6 Polyols Figure 1. This structure is characteristic of? Because the resulting structure is a crosslinked one, the MW of the resulting polyurethane is in?

Only linear polyurethanes have a? This high rigidity is an immediate consequence of the high crosslink density of the resulting polyurethane polymer [, 10, 11, 14, 36].
Several aspects of the profound in? In order to fully understand the role of the polyol structure on the properties of polyurethanes, the method of chemical insertion of oligo-polyol into the polyurethane macromolecules, will be discussed in Chapter 2, with the most important aspects of the chemistry of polyurethanes.
After that, the general and common characteristics of oligo-polyols for polyurethanes will be presented.
The later chapters will deal with a detailed presentation of the main types of oligo-polyols for polyurethanes, the chemistry and technology of these oligo-polyols including their manufacture.
The oligo-polyols are presented in two main groups: oligo-polyols for elastic polyurethanes and oligo-polyols for rigid polyurethanes.
Finally, a short chapter which is a generalisation of all the knowledge concerning the oligo-polyols, describes the relations between oligo-polyols structure and the properties of the?

The experimental purpose is to reclaim the spent catalyst and decrease the environment pollution. As a result, the saturated magnetizations of water-based and oil-based MFs are Their particle sizes are The prepared MFs would be used in separating low density metal from scrap, thereby decreasing the environmental pollution. Therefore, not only good magnetic fluid was prepared with the spent catalyst for the first time, but also the spent catalyst was recycled in an effective way to reduce environmental pollution.

The obtained polyols were characterized in terms of their composition, functionality, viscosity, and reactivity towards isocyanate. The main constituents of the obtained polyols included high functional polyphenolics based copolymers and low functional constituents — carbohydrate derived products based copolymers and polypropylene glycols.Please enter a valid ZIP Code.
