Self-Healing, Recyclable Syndiotactic 1,2-Polybutadiene-Based Thermadapt Shape Memory Polymers with Cold-Programmed Shape Memory Effect

, 2023
Shape memory polymers (SMPs), as a type of smart material, play a significant role in practical applications. Unlike the hot programming of SMPs, the cold programming of SMPs does not require preheating.

Fluorine-Terminated Liquid Polybutadiene: A Novel Approach to Enhancing Oil Resistance and Thermal Stability in Natural Rubber. [PDF]

Int J Mol Sci
Natural rubber (NR) has long been plagued by inferior oil resistance and poor thermal degradation at high temperatures. Despite these limitations, NR remains the most widely used elastomer to date.

Fabrication of β-cyclodextrin-crosslinked epoxy polybutadiene/hydroxylated boron nitride nanocomposites with improved mechanical and thermal-conducting properties

Journal of Materials Research and Technology, 2019
In this work, hexagonal boron nitride (hBN) was modified to introduce hydroxyl groups. The abundant hydroxyl groups in β-cyclodextrin (βCD) provide many reactive sites to form covalent links with epoxy groups in epoxy butadiene rubber (EBR).

Reprocessable Covalent Elastomeric Networks from Functionalized 1,4-cis-Polyisoprene and -Polybutadiene

, 2022
To obtain and maintain rubber properties such as elasticity, strength, creep, and chemical resistance, or stiffness over time, rubbers must be chemically cross-linked, mainly by sulfur vulcanization.

Cis-Polybutadiene-Natural Rubber Blends

, 1959
The preparation of 1:1 cis-polybutadiene-natural rubber blends has been shown to be feasible on a laboratory scale. Blends of this type have displayed hysteresis properties equivalent to the natural rubber control and have exhibited satisfactory modulus,

Impact modification of poly(caprolactam) by copolymerization with a low molecular weight polybutadiene [PDF]

, 1988
Caprolactam and a reactive, low molecular weight polybutadiene were polymerized in an autoclave, followed by post-condensation in the solid state. The rubber concentration was varied (0–30 wt%).

Graft Copolymerization : On the Structure of the Graft Phase and the Mechanism of Grafting Polybutadiene Rubber

, 1965
Polybutadiene rubber undergoes grafting by direct interaction with initiator radicals rather than by transfer with growing radical chains. The insolubility of the grafted rubber is probably caused by crosslinking, which competes with grafting.
