These polymers are man-made used for variety of applications such as food packaging, fibers, pipes, etc. <span style="color: rgb(245, 128, 56)">//Method of Linking Monomers:// Addition. The monomers of Plexiglass are linked through addition, meaning in order for two monomers to bond, a hydrogen must be broken off each of the monomers in order to form a large polymer rather then a single monomer. At this point, the two carbons will bond with bond with each other, and the process will repeat. //<span style="color: rgb(245, 128, 56)">Thermoset, Thermoplastic, Fiber, or Elasto<span style="color: rgb(245, 128, 56)">mer? <span style="color: rgb(245, 128, 56)">: //<span style="color: rgb(245, 128, 56)"> Thermoplastic. Plexiglass is thermoplastic, for it is a plastic that melts to a liquid under enough heat, and freezes to a brittle, glassy-like state when cooled enough. Thermoplastics are generally high weight polymers. <span style="color: rgb(245, 128, 56)">//Biodegradable, Recyclable, or Renewable?:// Recyclable!! <span style="color: rgb(245, 128, 56)">//Cross-linkage Occurrence:// Plexiglass does have the ability to cross-link between the methyl group and the ester group. The methyl group (see highlighted yellow area) is slightly more positive due to the presence of Hydrogen. The ester group (see highlighted blue area) is slightly more negative due to the two lone pairs and the more electronegative ares of Oxygen. <span style="font-size: 120%; font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif; color: rgb(0, 192, 255); text-align: center; display: block"><span style="color: rgb(25, 136, 230)">    <span style="color: rgb(25, 159, 225)">      <span style="font-size: 130%; color: rgb(0, 0, 0); font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif"> <span style="font-size: 120%; font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif; color: rgb(0, 192, 255); text-align: center; display: block"><span style="color: rgb(25, 136, 230)">    <span style="color: rgb(25, 159, 225)">    ** <span style="font-size: 130%; color: rgb(0, 0, 0)"> <span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif; color: rgb(242, 49, 133)"> __Physical and Chemical Properties__ **<span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"> <span style="font-size: 130%; color: rgb(0, 0, 0)"> <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif">                <span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif">Physical Properties: > Upon reaching its melting point, it can be formed formed or put into any shape. > >  <span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Trebuchet MS',Helvetica,sans-serif"><span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif"><span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"> <span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif"><span style="font-family: 'Trebuchet MS',Helvetica,sans-serif"><span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Lucida Console',Monaco,monospace"><span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif">Chemical Properties:    <span style="font-family: 'Lucida Console',Monaco,monospace"> > <span style="font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif"><span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif"> Temperature at Ignition in Presence of Flame is in between 550 and 570 degrees Fahrenheit > Upon ignition, Plexiglass burns vigorously and generates intense heat > Will only react with chlorinated hydrocarbons, aromatic solvents, ethyl and methyl alcohol, organic acids, > lacquer thinners, esters, and ketones. <span style="font-size: 120%; font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif; color: rgb(0, 192, 255); text-align: center; display: block"><span style="color: rgb(25, 136, 230)">    <span style="color: rgb(25, 159, 225)">    ** <span style="font-size: 130%; color: rgb(0, 0, 0)"><span style="display: block; font-size: 120%; text-align: left; color: rgb(242, 49, 133)"> __Practical and Industrial Uses__  **            <span style="color: rgb(245, 128, 56)"><span style="font-family: 'Palatino Linotype','Book Antiqua',Palatino,serif; color: rgb(0, 0, 0)">Plexiglass has countless uses.
