Mechanical properties of poly(ethylene terephthalate) modified with functionalized polymers

“…[2][3][4] The present study extended these previous investigations that focused on level of grafting to examine the effect of other variables, including PET molecular weight, SEBS molecular weight, and PET hydroxyl-to-carboxyl end group ratio. The results are summarized as follows:…”

“…5(a)]. 4,9 The size and shape of the preexisting craze were revealed by the boundary of the smooth region; in this example, the length of the craze was about 0.9 mm at fracture. At higher magnification, the region of craze fracture did not exhibit the fibrillated texture that is characteristic of fracture through the craze fibrils.…”

“…[1][2][3][4] The triblock copolymers in these studies had styrene end blocks and an ethylene/butylene midblock (SEBS) that was grafted with maleic anhydride. Improved properties with these and other blends of PET that incorporated functionalized polymers [5][6][7][8] were consistent with in situ formation of a graft copolymer by reaction with PET end groups.…”

“…3,4 In contrast, particle size was strongly dependent on elastomer functionality: the higher the functionality, the smaller the particle size and the narrower the particle size distribution. These trends were at-tributed to an increase in the degree of grafting.…”

Preparation and characterization of poly(butadiene-stat-styrene)/poly(styrene-stat-acrylonitrile) structured latex particles

“…[9][10][11][12][13] Since PBd is an excel-On the other hand, the shell polymer is selected grafting of the shell polymer on the core polymer were controlled to study the effect of these factors based on the good compatibility between the shell and the polymer matrix to achieve a certain dison toughening properties. In a separate paper, 25 the mechanical and toughening properties of PC persibility and good adhesion with the matrix.…”
