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.

Formation of Multiple Networks in Cis-1, 4-Polybutadiene: Dynamical Viscoelasticity, Gel Content and Cross-Link Density

IOP Conference Series: Materials Science and Engineering, 2020
The formation of multiple networks of cis-1, 4-polybutadiene rubber (BR) with sulfur and carbon black (CB) were discussed by analysing the curing curve, gel content, cross-linking density (XLD) and dynamic viscoelasticity.

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,
