Thermally Bistable Stiff Stilbene Photoswitches and Polymer Applications

The Chemical Record, Volume 26, Issue 6, June 2026.
Thermally stable photoswitches offer new opportunities for controlling polymer structures and functions under nonequilibrium conditions. This Personal Account highlights stiff stilbene (SS) and sterically hindered stiff stilbene (HSS) photoswitches, which combine large structural changes with exceptional thermal bistability.

Clustering and nanoscale vitrimeric behavior in telechelic polybutadiene model vitrimers

Despite the promise of vitrimeric materials applications, there are many aspects that remain poorly understood. To advance the fundamental knowledge of these materials, model systems of well-controlled composition are needed. Here we report the synthesis

Mechanical Properties of Blends of Crystallizable Polybutadienes Containing Amorphous Polybutadiene Diblock Copolymers

, 1994
Tensile failure properties of syndiotactic 1,2 polybutadiene/trans 1,4 polybutadiene crystalline blends are improved by addition of 5–10% amorphous 1,2 polybutadiene/1,4 polybutadiene diblock copolymer. The effect of block molecular weight and microphase

Synthesis and characterization of polybutadiene-containing polyurethanes.

, 1981
Several segmented polyurethanes have been synthesized, based on a variety of hydroxyl-terminated polybutadienes (HTPB) , two of which included a free radically polymerized, branched polybutadiene with an average functionality of 2.1, and a hydrogenated ...

A theory for the thermal conductivity of highly viscous chain-like polymer melts [PDF]

AIP Advances
Polymers play a key role in many modern electronic applications. Conventional pure (unfilled) polymers, with inherently low thermal conductivity (6×106Da) of polyethylene, polyethylene oxide, and polybutadiene may exhibit giant thermal conductivity ...

Phase behavior, morphology and interfacial structure in thermoset/thermoplastic elastomer blends of poly(propylene glycol)-type epoxy resin and polystyrene-b-polybutadiene

, 2001
Thermoset/thermoplastic elastomer (TPE) blends of poly(propylene glycol) (PPG)-type epoxy resin (ER) and a diblock copolymer, polystyrene-b-polybutadiene (SB, with 30% styrene content), were prepared using 4,4′-diaminodiphenylmethane (DDM) as curing ...

Permanganate Oxidation of Polybutadiene Rubbers

, 1951
In view of the failure to obtain quantitative yields of the expected carboxylic acids by permanganate oxidation of the several butadiene polymers studied, definite conclusions about their structures cannot be made.

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.
