Therefore, to terminate the polymerization, a quenching agent must be added, such as a strong acid to protonate the polymer, or a nucleophile to add an end cap the polymer. If the π-complex is too weakly bound, termination of polymer chains can occur before a quenching agent is added, causing lower molecular weight polymers to form.
The total number of radicals delivered to the system by the initiator during the course of the polymerization is low compared to the number of RAFT agent molecules, meaning that the R group initiated polymer chains from the re-initiation step form the majority of the chains in the system, rather than initiator fragment bearing chains formed in ...
AMPS is made by the Ritter reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water. [2] The recent patent literature [3] describes batch and continuous processes that produce AMPS in high purity (to 99.7%) and improved yield (up to 89%, based on isobutene) with the addition of liquid isobutene to an acrylonitrile / sulfuric acid / phosphoric acid mixture at 40°C.
Key takeaways. The numbers on a credit card help identify the credit card network, the company that issued the card and the cardholder. Credit card numbers are either 15 or 16 digits, with each ...
Working Assets' first product was the Better World Credit Card. After the United States deregulated telephone service, the company introduced Working Assets Long Distance in 1991. In 2000, it also became a mobile virtual network operator, operating as Working Assets Wireless. The company renamed this division to CREDO Mobile in
The Japanese company Showa High Polymer, built in 1993 a semi-commercial plant able to produce 3,000 tons of polymer per year. [13] Sold under the tradename Bionolle, these polyesters are synthesized via melt condensation polymerization followed by a chain-extension with a diisocyanate . [ 14 ]
The plastics industry manufactures polymer materials—commonly called plastics—and offers services in plastics important to a range of industries, including packaging, building and construction, electronics, aerospace, manufacturing and transportation. It is part of the chemical industry.
Polymer chemistry is a sub-discipline of chemistry that focuses on the structures, chemical synthesis, and chemical and physical properties of polymers and macromolecules. The principles and methods used within polymer chemistry are also applicable through a wide range of other chemistry sub-disciplines like organic chemistry , analytical ...
