Abstract

Results of the study of rheological characteristics of dispersion-filled polymer composition materials (DFPCMs) based on low-density polyethylene (LDPE) and glass beads of ShSO-30 brand are given. Rheological properties of dispersion-filled polymer composition materials are considered for the first time in context of formation of the disperse phase in the system of functional division of polymer matrix (φp = θ + B + M), which are described within the lattice theory (HL, IC, TL, and CL) and generation of disperse systems possessing various structures (DS, LFS, MFS, and HFS) in terms of generalized and reduced parameters (θ, aav/d, θ/B, and θ/Sf). A relationship of rheological characteristics of DFPCMs to generalized parameters and types of disperse structure according to their classification (DS, LFS, MFS, and HFS) is shown for the first time. Such approach allows one to predict the rheological properties of all DFPCMs upon generation of various types of disperse structures using the disperse phase (filler) with known geometrical sizes (d), particle shape (ke), specific surface (Ssp), and maximum packing density (content (kpacking and φm)) and specified polymer matrix.
