Carboxyl-terminated butadiene acrylonitrile (CTBN) liquid rubber/epoxy (diglycidyl ether of bisphenol-A: DGEBA) / diamino diphenyl methane (DDM) resins, in which CTBN was 60 wt % as the major component, were formulated to evaluate the damping and adhesive properties.
Acrylonitrile and derivatives, such as 2-chloroacrylonitrile, are dienophiles in Diels–Alder reactions. Acrylonitrile is also a precursor in the industrial manufacture of acrylamide and acrylic acid. Health effects. Acrylonitrile is highly flammable and toxic at low doses. It undergoes explosive polymerization.

Carboxyl-modified multi-walled carbon nanotubes (MWCNT–COOHs) as nanofillers were incorporated into diglycidyl ether of bisphenol A (DGEBA) toughened with carboxyl-terminated butadiene-acrylonitrile (CTBN). The carboxyl functional carbon nanotubes were characterized by Fourier-transform infrared spectroscopy and thermogravimetric analysis.

There are 90 carboxyl terminated liquid butadiene acrylonitrile rubber suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply 100% of carboxyl terminated liquid butadiene acrylonitrile rubber respectively.
Carboxyl-terminated butadiene-acrylonitrile (CTBN) rubber is a telechelic copolymer containing polar nitrile group (–CˆN) in the main chain. Nitrile group has strong chemical bonding with PF and epoxy resin, thus liquid CTBN shows good compatibility with them and can be uniformly dispersed in PF  .
Six blend samples were prepared by physical mixing of epoxy resin with varying concentrations of liquid carboxyl-terminated butadiene acrylonitrile (CTBN) copolymer having 27% acrylonitrile content.
Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). ABS is amorphous and therefore has no true melting point.

carboxyl-terminated butadiene-co-acrylonitrile (CTBN). McGarry et al used CTBN of molecular weight 3000 and various DGEBA epoxies cured with piperidine. Kinloch et al revealed a dynamic dependency in the DGEBA/CTBN/piperidine system by calculating the impact fracture toughness at different strike velocities and obtaining a near two-fold increase in toughness.

The great majority of the studies,,,,,, involve the chemical modification of epoxy resin with reactive liquid rubber, particularly carboxyl-terminated butadiene acrylonitrile copolymer (CTBN). The micro-structure formed consists of an elastomeric phase finely dispersed in the epoxy matrix with the elastomeric particle diameter of few micrometers or zero.
3D Printing of Carbon Fiber-Reinforced Composites. 3D printing is a type of additive manufacturing that can be used to rapidly fabricate components with highly customizable geometries, most typically using a layer-by-layer fabrication process. 3D pri...
elastomers widely used in the modification of thermosets are: carboxyl terminated butadiene acrylonitrile (CTBN), vinyl terminated butadiene acrylonitrile (VTBN), polyurethane, polyvinyl butyral (PVB) . The elastomer particles, dispersed in a resin, regulate the fracture mode and prevent brittle fracture of the resin by inducing plastic

Acrylonitrile butadiene rubber, usually shortened to nitriles, are important elastomers. The acylonitrile (AN) content usually varies between 15 and 45 percent. NBR grades with high AN content have better oil and abrasion resistance, whereas grades with low AN content have better low temperature flexibility and resilience.
