In the review, the carbamide-formaldehyde oligomer was taken as an object of research. Carbamide-formaldehyde oligomer is used as a co-ordinator for the preparation of various compositions, such as many oligomers. But this oligomer also has certain disadvantages that it is intended to be remedied by modification. After the modification, the function of the oligomer has increased, allowing it to be used as a co-ordinator for the preparation of various composites. Numerous research works were carried out on the modification of phenol-formaldehyde and epoxy-dian oligomer in the chair, as well as the study of key indicators and use of them as a co-ordinator for the preparation of various composites on the basis of them and positive results were obtained. As a modifier in research, organic compounds such as nitrogen, chlorine, bromine, sulfur, etc. were used. Carbamide-formaldehyde oligomer is modified by the organic compounds. Our goal is to produce compositions with higher performance indicators, including various nanoparticles of the new modified carbamide-formaldehyde oligomer.
