to neutralize the HCl released each time a new amide bond was formed. Slime was made from the reaction of poly(vinyl alcohol), PVA, and borax, creating a cross-linked polymer. All three polymerization reactions were successful in creating a solid polymer. The radical chain addition reaction created a white fibrous solid called polystyrene, the condensation reaction created a white rubbery solid called nylon, while the cross-linked polymerization reaction created an orange oozy solid called slime. Polystyrene and Nylon were tested to check 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

    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.
