On this examine, the superabsorbent polymer has been synthesized by way of inverse suspension polymerization. The absorption experiments for water and salt water showed that the operating circumstances equivalent to monomer dosages, neutralization degree, oil-water ratio, temperature, and the cross-linking agent had great results on the water absorption. The optimum reaction conditions had been as follows: the cellulose monomer ratio: 1 : 10, neutralization diploma: 75%, oil-water ratio: 3 : 1, and reaction temperature: 70°C. The water and salt water absorption price can attain as high as 859 g/g and 72.48 g/g, respectively. Moreover, the moisture resistance of the resin handled by ECH and DEG was improved considerably. The moisture resistance confirmed one of the best when the addition of ECH was 15%, and it increased with the increasing quantity of DEG, but when the dosage of DEG exceeded 5%, the particles among the many resin adhered seriously.
Finally, one named Leo Baekeland decided perhaps his ineffective by-product wasn’t so ineffective in any case. His work resulted in a plastic that could be permanently squished into a form utilizing stress and high temperatures. Because the identify of this plastic, polyoxybenzylmethylenglycolanhydride, wasn’t very catchy, advertisers referred to as it Bakelite. Bakelite was made into telephones, youngsters’s toys, and insulators for electrical gadgets.
