Abstract

The processes of structure formation and features of polymer composites with special properties are investigated, the main kinetic processes that have a decisive influence on the structure formation and properties of polymer composites are identified. The expediency of considering kinetic (transient) processes as a necessary and sufficient sign of the structure formation of a thermosetting is substantiated. A mathematical method for the synthesis of polymer composite materials of increased density using the quality functionals of kinetic (transient) processes is proposed. The proposed mathematical methods and models allow to effectively solve the problem of plasticization and modification of high-viscosity polymers, as well as to carry out multi-criteria synthesis of composite materials with strictly specified parameters of structure and properties using the quality functionals of kinetic (transient) processes.

Summary

Introduction

Polymer concretes and polymer mortars have been widely introduced into construction practice They are used for corrosion protection of building structures (mastics, putties, adhesives, polymer concrete, polymer mortars).Polyester polymer concretes are of considerable interest. Polymer concretes and polymer solutions based on unsaturated polyester resins are used for the installation of monolithic self-leveling floors and all kinds of protective coatings. Most polyester resins of domestic and foreign brands cannot be used without modification for installing monolithic floors and protecting technological containers from aggressive influences. This is due to their high shrinkage with a significant modulus of elasticity, which leads to cracking of thin coatings based on such resins and to peeling of thick ones.
