Abstract
The use of traditional paints and varnishes containing organic solvents in their composition causes significant harm to human health and leads to environmental pollution. In this regard, an actual problem is the creation of new environmentally friendly paints and varnishes that are applied to the painted surface without the use of organic solvents. As a result of the research, a method has been developed for producing 1,3-pentadiene polymers, which can be used in the manufacture of thermoplastic paints for road marking. The method consists in carrying out the process of cationic polymerization of 1,3-pentadiene using a catalytic system based on ethylaluminum sesquichloride. It was found that the polymer chain of the synthesized poly-1,3-pentadiene consists mainly of 1,4-trans- and 1,2-trans-units and is characterized by reduced unsaturation. The introduction of a modifier, diisopropyl ether, into the catalytic system makes it possible to obtain completely soluble 1,3-pentadiene polymers with the required softening point temperature.
