their solubility in Acetone, Toluene, and Ethanol. Both polymers were insoluble in all three liquids. Neither Polystyrene nor Nylon dissolved in Acetone, Toluene or Ethanol. This shows that polymerization reactions were completely successful and that the polymers were formed. The monomers can no longer dissolve in the solution after undergoing the polymerization reactions since the polymers are not soluble. Had the reaction not fully formed polymers, there would be some dissolving of the monomers. There could have been many sources of error in this experiment. During the preparation of polystyrene, if the mixture is not heated in boiling water for long enough ( approximately 1 hour) or its is not allowed to cool to room temperature before breaking the test tube, it might

disrupt the radical polymerization process. When preparing Nylon-10,6, if sebacoyl chloride is not poured slowly down the inside of the beaker wall, two layers might not form, and thus the condensation reaction would not take place completely. When making slime, it is imperative to stir the mixture properly to get the consistency of slime and failure is doing so can lead to an improper representation of the polymer. Conclusion Polystyrene, Nylon-10,6 and slime were made through three different polymerization reactions. Styrene underwent radical chain addition polymerization with the help of Benzoyl peroxide which acted as the initiator. Nylon-10,6 was produced through a condensation polymerization reaction while Slime was made through a cross-polymerization reaction. Polystyrene and Nylon-10,6 were tested for solubility in Acetone, Toluene, and Ethanol to check for the success of the polymerization reactions. Both polymers did not dissolve in the three mixtures, indicating that the polymerization reactions were completed successfully. Monomers in a polymer cannot dissolve in the mixtures, but had the polymer not fully formed, some of the solid would have dissolved. Since no solid dissolved, it can be concluded that all three polymerization reactions were accomplished.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
