AbstractCement board reinforced with basalt fibers were prepared by using polymer compounds, 5% of water-based of isocyanate-polyester polyol prepolymer blend was used as a fixed percentage, and the rates of basalt fiber used were 5%, 7.5%, 10%, 12.5%, an... see more

The study deals the effect of increasing NCO/OH molar ratio on the physico-mechanical properties of isocyanate terminated polyurethane prepolymer. The prepolymer was prepared using castor oil and toluene-2,4-diisocyanate. The NCO/OH molar ratio has been v... see more

Amide and ester type polyols were synthesized from rapeseed, sunflower and castor oils, and two types of ethanolamine (diethanolamine and triethanolamine) at different molar ratio. Poly(urethane amides) and polyester urethanes based on the synthesized pol... see more

A series of polyurethane-polyisocyanurate (PU-PIR) foams synthesized from PET-waste-derived aromatic polyester polyols (APP) was studied using thermogravimetric analysis, Cone calorimeter and burning tests. The effect of chemical structure of the APP cont... see more

Bagmut I. Yu., Popova T. M., Titkova A. V., Philipchenko S. M., Shepylieva N. V. The influence of sub-toxic dose xenobiotic on immune response of experimental animals = ????? ???????????? ??? ????????????? ?? ?????? ????????? ? ????????????????? ?????? = ... see more

Amide and ester type polyols were synthesized from different kinds of tall oil and two types of ethanolamine (diethanolamine and triethanolamine). Poly(urethane amides) and polyester urethanes based on the synthesized polyols were prepared. The influence ... see more

Poly (ethylene terephthalate) (PET) waste bottles were recycled to prepare RPUFs (rigid polyurethane foams) by using propylene glycol (PG) in different glycol/polymer molar ratios. The glycolysis products were characterized, after that, they reacted with ... see more


This paper proposed adsorbent development by synthesizing polyurethane foam (PUF) using a simple method, mixing polyol with isocyanate and adding fillers of bentonite and magnetite to the PUF matrix. The study's main objective was to produce a PUF-based a... see more
