Introduction Innovations in technology made possible the creation of the bouncing ball, creditable to the chemist Norman Stingley. This bouncing ball originated from the concepts and shape of the regular toy ball. [1]. Balls have been in the industry for ages, as it needs chemical processes to be produced. As a result of innovation and optimization of processes the bouncing ball was invented using rubber at first, but produced by polymerization and use of plastics in the present. [2] Polymerization is not something that started long time ago, but became one of the most important chemical processes in the chemical industry and the modern world. Polymers are subdivided in two types, natural and human made commonly known as synthetic polymers.

It is important to note that sodium borate was hydrolyzed in the solution resulting in borate that reacts with the polyvinyl alcohol.
Evaluation, determined by the research group, had to be done on the material to test its properties. The material had to have the optimal combination of the reactants, and needed to have the ability to retain its texture, shape and functionality in extreme weather conditions because the the destination of the final product will be Florida, Alaska and New Mexico, meaning that the temperature changes will be great, ranging from -3°C to 22°C [5] [6]. Other properties that were assessed were bouncing height and elasticity, to determine the optimal combination of reactants. All of these properties are to be tested with procedures determined by the research …show more content…
It was noticed that as a reduction of the acetate, the heat resistance increases because the ball retains its shape as more acetate was added, so if the ball had a much destroyable texture, the heat would dissolve the ball more. Increasing the acetate back to trials 1 level but decrease the alcohol on the solution, the material became much less resistant to heat, so the ball bounced smaller heights.
Conclusions
In general it was concluded that the most optimal mixture was ball #5 since in average it bounces more than the average for the 3 balls combined. Its elasticity results revealed that the material is well bonded due to its length when pulled apart. In the cold and heat resistance tests there is an average 10 cm for the cold resistance test and 9.3 for the heat resistance test, meaning that the material is optimal for the three temperature ranges for the climates in which it will be exposed. To perfect the material, more trials could have been done to determine if high or low levels of sodium borate and high or low levels of cornstarch could have affected the materials assessment
