Bonding of Polyethylene to Metals and Rubber with Hydrogenated Polybutadiene

, 1962
The adhesive composition based on hydrogenated unbranched 1,4-polybutadiene gives a high bond strength between polyethylene and brass, and brass-plated metal, and rubber.

Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, EarlyView.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

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.

Field‐Cycling NMR Relaxometry in Tire Elastomer Science

Magnetic Resonance in Chemistry, EarlyView.
Field‐cycling NMR relaxometry has established as an ideal tool to investigate multiscale polymer dynamics. Here, we review and discuss applications on elastomers and elastomer compounds of interest for the tire industry to obtain information on segmental dynamics and on polymer dynamics over different regimes as a function of chain length in polymer ...

Vulcanization of Elastomers. 44. Vulcanization of Polybutadiene with Cumyl Peroxide. I.

, 1965
Cumyl peroxide vucanization of cis-1,4 polybutadiene with 2“3 per cent 1,2 addition was compared with that of natural rubber. The essential findings are: 1) In both rubbers, cumyl peroxide decomposed at exactly the same rate.

"Progress in inorganic nano-fillers reinforced cis-1,4-polybutadiene rubber composites "

Hecheng xiangjiao gongye
The mechanical properties of unmodified cis-1,4-polybutadiene rubber were not satisfactory, and different types of reinforcing agents had different effects on the mechanical properties of cis-1,4-polybutadiene rubber.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Effect of recycling on mechanical and physical properties of polycarbonate/acrylonitrile–butadiene–styrene/poly(methyl methacrylate) (PC/ABS/PMMA) blends

Polymer International, EarlyView.
The 100% recycling of optimal polycarbonate/acrylonitrile–butadiene–styrene/poly(methyl methacrylate) (PC/ABS/PMMA) blends, identified through the mixture design, over multiple successive cycles provides valuable insights into their life cycle. Subsequently, chemical, rheological, thermal and mechanical characterizations will be carried out to evaluate

Infrared microspectroscopic study of the thermo-oxidative degradation of hydroxy-terminated polybutadiene/isophorone diisocyanate polyurethane rubber

, 2007
Hydroxy-terminated polybutadiene/isophorone diisocyanate (HTPB-IPDI) polyurethane rubber that was aged in air at elevated temperatures has been studied by infrared microspectroscopy.
