Consider the properties of the following two polyethylene samples. Sample 1 was produced by a high pressure process while sample 2 was synthesized using a catalyst. Evaluate the following statements I. Sample 1 is more branched than sample 2 II. Sample 2 is more isotactic III. Sample 2 would be more appropriate for making packaging for detergents. It is correct what is stated in

Construct the structure of isotactic polypropylene by dragging the appropriate groups onto the wedge-and-dash bonds. Some groups may not be needed. (Remember the abbreviation Me = CH3 or methyl.)

Calculate the approximate molar mass of a polyethene sample, the average chain length of which is 50 000carbon atoms.

Which of the following statements is false regarding polymers? Pick one answer.     A. addition polymers are produced by successive addition reactions     B. condensation polymers require water to combine monomers     C. polyethylene is the most common addition polymer     D. polymers can be synthetic or natural

15. Explain the below diagram using plastic and a rubber as an example [5] Stress (MPa) Toughness Strain Break Figure A1.12. The toughness of polymer material.

I keep thinking the plastic sulfur is S8 or an Sx polymer. I'm leaning more towards the polymer of sulfur since when you heat the sulfur, it breaks its cyclic bond and makes these long chains but I'm completely confused.

calculate the number of monomers in a 50 gram empty milk jug made from 100% high density polyethylene

Draw the structure of the polymer which would form when the following molecules react. Assume you have n moles of each reactant.
