Make a chart with e on the x-axis (1 – 10 gpa) and yield strength on the y-axis (10 – 100 mpa). select polypropylene (pp) and its various grades by applying a ‘tree’ stage selecting polymers – thermoplastics – pp (folder). label at least 10 records on the chart (from the bottom, middle, and top). insert the chart below, and then explain the trends you see. discuss the effects of 1) homopolymer versus copolymer, 2) ‘neat’ homopolymer versus additives, and 3) additives of particles versus fiber
