Title : Compositions on the basis of modified phenol-formaldehyde oligomers
In order to obtain desired properties of oligomers, modification process is used to change their structure and composition. In this matter, using traditional technology equipments and methods is more suitable. Lately to eliminate deficiencies of known oligomers, the process of modification with compounds of different nature is broadly studied. It is not always possible to reach the properties given for the particular oligomer material during the synthesis of oligomer material in industrial conditions, moreover, these processes are not always economical enough. Therefore, the modification processes of traditional industrial oligomer are being investigated more intensively with the purpose of obtaining oligomer compositions on their base with the given properties. In solution of this problem, great attention is being given to oligomer materials on the base of phenol-formaldehyde oligomers having available wide raw material base and reactivity, heat-resistance, satisfactory dielectric properties and cake formation ability. However, this oligomer has a number of disadvantages: low molecular mass, high flow in uncured state, brittleness, presence of free phenol in the composition and so on.
- The audience will learn about the modification process of phenol-formaldehyde oligomers with organic compounds and use this process in their research and teaching.
- It is possible to eliminate the deficiency of phenol-formaldehyde oligomers using our modification process and most importantly, as a result, the amount of free phenol is decreased five times.
- They will learn about obtaining environmentally friendly coating and adhesives using oligomers as a liaison and biopolymers as a filler.
- The obtained environmentally friendly compositions based on oligomers may be used in many different fields of the industry.
