Thermo‐Mechanical Evaluation of Novel Composite Propellant Formulations Based on Styrene‐Ethylene/Butylene‐Styrene Block Copolymer

Propellants, Explosives, Pyrotechnics, Volume 50, Issue 11-12, Page 117-126, December 2025.
ABSTRACT Two novel composite propellant formulations have previously been produced from a binder consisting of the thermoplastic elastomer styrene‐ethylene/butylene‐styrene (SEBS) and a solid filler, either ammonium perchlorate (AP) or 1,3,5‐trinitro‐1,3,5‐triazinane (RDX).

Large Supramolecular Patterns in Photoactive Chiral Liquid Crystals for Light‐Controllable Soft Micromechanical Systems

Small Structures, Volume 6, Issue 12, December 2025.
Revolving chiral patterns are induced by an ultraviolet light beam in frustrated films of photoactive chiral nematics. The uniformity and regularity of the rotation depend on the ratio of the pattern size to the diameter of the light spot. The rotation is interrupted when this ratio reaches about eight.

Synthesis of HTPB using a semi-batch method

Materiały Wysokoenergetyczne / High Energy Materials, 2020
Hydroxyl-terminated polybutadiene is widely used in industry for both civil and military applications. In munitions, HTPB is mostly used as a binder for heterogenic rocket propellants and as a component of plastic bonded explosives, as well as a phlegmatizer in explosives sensitive to friction and impact.

Sustainable Synthesis of Polyurethane Using Hydroxyl‐Terminated Polybutadiene (HTPB) Derived From the Degradation of Butadiene Rubber with Fatty Alcohol

Macromolecular Materials and Engineering, Volume 310, Issue 11, November 2025.
This study proposes a synthesis route for polyurethanes (PUs) derived from bio‐based polyols. The polyols were obtained through metathesis depolymerization of butadiene rubber using fatty alcohol (a castor oil derivative) as a chain transfer agent to produce hydroxyl‐terminated polybutadiene (HTPB).

Exploring Effect of a Ternary Filler System on Low Hysteresis and Improved Wet Grip Properties of Sustainable and Fuel‐Efficient Tyre Tread Formulations

Macromolecular Materials and Engineering, Volume 310, Issue 10, October 2025.
This study investigates the mechanical, thermal, and dynamic mechanical properties of an eco‐friendly, green tyre tread compound, focusing on a ternary filler (CB, exfoliated graphite/modified silica) system. These findings establish modified silica as a key enabler in the development of next‐generation green tyres, offering a high‐performance ...
