ABSTRACT

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 are 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.These investigations are being carried out in some directions and the more vital of them in modification of phenol-formaldehyde oligomers with the purpose of regulation of the above mentioned disadvantages and giving more functionality to these oligomers.

The development of production and the compositions based on biopolymer are expanding very fast. In order to obtain ecologically friendly composition, as a liaison modified phenol-formaldehyde oligomer and as filler, biopolymers were used. Main properties of obtained coating and adhesive compositions were studied. New composite, ecologically friendly coating and adhesive compositions are recommended to be used in many fields of industry.  The need for improvement of new compositions is also very high. Main parts of molecular structure consist of cellulose and lignin. Almond shell powder taken as additive affect is on improvement of physical - mechanical features of the painting composition. Thermal properties of filler have been studied by means of thermogravimetric analysis (TGA). In order to identify functional groups of compounds used IR spectroscopy.
