DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 55 Bis(vinylarylalkyl) polysulfides and curable, low-odor (vinylarylalkyl)-terminated polysulfide copolymers, useful in coatings, sealants, and caulking compns. with low cold flow, ard manufd. from alkali or alk.-earth polysulfides, 4-vinylbenzyl chloride (I) [1592-20-7], and halogenated alkanes (for the copolymers). Thus, 122 g I was added in 1 h to a compn. contg. hydrated Na2S 96, S 37.5, hydrated MgCl2 8.5, NaOH 3.6, and 30% Na lauryl sulfate 10 g at 70°, and the mixt. was heated 1 h at 70° to give bis(4-vinylbenzyl) tetrasulfide (II) [90328-19-1]. A 1.5-mil-thick coating of II on a steel panel was baked 10 min at 200° to give a polymer [29296-32-0] coating which exhibited no loss of gloss after 100 MEK double rubs, Knoop hardness 32, and no effect after 24 h at 150° in a humidity chamber. .

DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) We examd. the syntheses and photochem. properties of the polymers with pendant azobenzene (AZ) and anthracene (AT) moieties. The photochem. reactions of the obtained polymers were performed in the film state with 250-W high-pressure mercury lamp. The photochem. valence isomerization of trans-AZ and photochem. dimerization of AT were obsd. to proceed smoothly, resulting in giving the cis-AZ and AT-dimer, resp. The stored thermal energy of the irradiated polymers was evaluated by differential scanning calorimetry to be 1.01-27.There are some commonly used reagents with their cas registry numbers 1468-95-7 and 29296-32-0 in this article.70 kJ/mol. Furthermore, the change in the refractive-indexes (Dn's = 0.010-0.075) was obsd. to occur before and after the photochem. reactions. .
