Factors Controlling the Rate of Photodegradation in Polymers: The Effect of Temperature on the Photodegradation Quantum Yield in a PVC Polymer Containing Metal–Metal Bonds in the Polymer Chain

Tetracarbonylbis(η5-cyclopentadienyl)bis(diphenylphosphine)dimolybdenum(Mo—Mo) hexane solvate

“…For related literature, see: Adams et al (1997); Chen et al (2004); Daglen et al (2007); Shultz et al (2008); Tenhaeff & Tyler (1991); Tyler (2003); Van der Sluis & Spek (1990); Wilson & Shoemaker (1957).…”

“…We previously reported the synthesis of photodegradable polymers that contain metal-metal bonds along the main chain (Tenhaeff & Tyler, 1991;Tyler, 2003). The metal-metal bond provides a convenient spectroscopic handle for monitoring the effect of external parameters as tensile stress (Chen et al, 2004) and temperature (Daglen et al, 2007) on the rate and onset of polymer backbone degradation. Recent work describes the preparation of phosphine-substituted dimeric molydenum complexes as precursors for step polymerization (Shultz et al, 2008).…”

Tetracarbonylbis(η5-cyclopentadienyl)bis[(dec-9-en-1-yl)diphenylphosphine]dimolybdenum(0)(Mo—Mo) tetrahydrofuran disolvate

“…For related literature from our group in this area, see: Chen et al (2004); Daglen et al (2007); For other compounds containing Mo-Mo single bonds, see: Wilson & Shoemaker (1957); Shultz et al (2008). Selected bond lengths (Å ).…”

“…In an on-going mechanistic study in our lab we have examined the effects of external parameters, such as mechanical stress (Chen et al, 2004) and temperature (Daglen et al, 2007), on the rate and onset of polymer degradation using polymers with metal-metal bonds in the main chain. Such polymers are synthesized from functionalized dimeric metal carbonyl complexes.…”

Chitosan withPVC Polymer for Biomedical Applications: A Bibliometric Analysis

“…CS is a polysaccharide gotten from chitin; chitin is the second most bountiful polysaccharide on the planet, after cellulose [7]. The presence of amino gatherings in the CS structure may be protonated-giving solvency in weakened acidic watery arrangements, a few amazing properties of chitosan offered novel occasions to the advancement of biomedical applications [8], [9]. CS is biocompatible, biodegradable and non-poisonous, so it tends to be utilized as clinical applications as antimicrobial and wound mending biomaterials [10].…”
