VULCANIZATION WITH SOME ORGANIC POLYSULFIDES

Theory & Practice Of Vulcanization

Combination of Gelatin with Some Organic Bases

I t is known that the alkaloids are very strong poisons. Their poisoning power can be compared only with that of the glucosides, the hormones, the saponins, HCN, and some bacterial toxins. The alkaloids are sufficiently studied physiologically, and in relation to their chemical structure, but what chemical substances enter in combination with them in the body and in the cell is wholly obscure. ...

Critical behaviour for vulcanization processes

2014 We consider a polymer melt, with polymerization index N and a fraction p of cross linked monomers, for values of p close to the gelation threshold (p = 03C1c + 039403C1). Using a Ginsburg argument, we find that (in three dimensions) the Flory theory is qualitatively correct whenever N > (03C1c/039403C1)3. For shorter chains the critical exponents are expected to be of the percolation ...

Hydrogen sulfide and polysulfides as signaling molecules

Hydrogen sulfide (H2S) is a familiar toxic gas that smells of rotten eggs. After the identification of endogenous H2S in the mammalian brain two decades ago, studies of this molecule uncovered physiological roles in processes such as neuromodulation, vascular tone regulation, cytoprotection against oxidative stress, angiogenesis, anti-inflammation, and oxygen sensing. Enzymes that produce H2S, ...
