What structural properties allow alkenes to serve as good monomers for polymerization reactions?
What are the primary types of chemical bond changes which occur during polymer synthesis employing alkenes monomers?
Alkenes are key organic compounds which serve in many applications including the synthesis of polymers. The electrons contained in alkene monomers are bonded through weak pi-bonds can be broken to form strong sigma bonds to other ...
This solution explains the characteristics of alkenes and the conditions required to form polymers.
1. Why a polymer such as polybutadiene can be cross-linked, however a polymer such as polyethylene cannot be cross-linked. Please make reference to what it is about the chemistry of the repeating units that allows for the formation of cross-links.
2. Car tires are made of vulcanized rubber, which is a crosslinked polymer formed through the addition of sulfur and heat to form disulfide bridges between polymer chains. Car tires are actually fairly difficult to recycle when compared to other non-crosslinked polymer products such as plastic bottles. Consider why this might be the case, and give your thoughts.
3. Shown attached is a schematic representation of the water-ethanol phase diagram.
Making reference to the phase diagram, explain in a few sentences how one could enrich a solution of 15 percent ethanol - 85 percent water to a composition of 60 percent ethanol - 40 percent water. Be qualitative in your description, not quantitative.
Furthermore, explain why this procedure could not be used to reach a completely pure composition of 100 percent ethanol.View Full Posting Details
