Styrene-ethylene-butylene polymer

As more complex multicomponent blends are being developed for commercial appHcations, new approaches are needed for morphology characterization. Often, the use of RuO staining is effective, as it is sensitive to small variations in the chemical composition of the component polymers. For instance PS, PC, and styrene—ethylene/butylene—styrene block copolymers (SEES) are readily stained, SAN is stained to a lesser degree, and PET and nylons are not stained (158,225—228). [Pg.418]

Sulfonation is very useful chemical modification of polymer, as it induces high polarity in the polymer changing its chemical as well as physical properties. Sulfonated polymers are also important precursors for ionomer formation [75]. There are reports of sulfonation of ethylene-propylene diene terpolymer (EPDM) [76, 77], polyarylene-ether-sulfone [78], polyaromatic ether ketone [79], polyether ether ketone (PEEK) [80], styrene-ethylene-butylene-styrene block copolymer, (SEBS) [81]. Poly [bis(3-methyl phenoxy) phosphozene] [82], Sulfonated polymers show a distinct peak at 1176 cm"1 due to stretching vibration of 0=S=0 in the -S03H group. Another peak appears at 881 cm 1 due to stretching vibration of S-OH bond. However, the position of different vibrational bands due to sulfonation depends on the nature of the cations as well as types of solvents [75, 76]. [Pg.147]

Other companies have also produced condoms made from the polymer styrene-ethylene-butylene-styrene which has the advantage of being even stretchier than polyurethane, thereby reducing the risk of tearing during use. There are also condoms lubricated with a combination of silicone oil and nonoxynol-9 which acts as a spermicide. Nonoxynol-9 is also used as a surfactant in cosmetic products, but it has the ability to interfere with the acrosomal membrane which covers the head of a sperm, causing it to become paralysed, which is why nonoxynol-9 has been widely used in lubricants for condoms and es-...

Kraton 1101 (styrene-butadiene-styrene) and Kraton 4609 (styrene-ethylene-butylene-styrene) were obtained from Shell Chemical Co. (8). The polymers were purifed by dissolving in toluene and precipitating in methanol. IR spectra were obtained using a Perkin-Elmer Model 299B spectrophotometer. Electron micrographs were taken using a Phillips EM 400T instrument. Samples for transmission electron microscopes were either microtomed or casted from toluene. [Pg.498]

The silicone semi-lPNs consist of mixing a hydride-containing silicone prepolymer and a vinyl functionalized silicone polymer into a thermoplastic matrix such as PA, PBT, thermoplastic polyurethane (TPU) or styrene-ethylene/butylene-styrene (S-EB-S) block copolymer elastomer. The two silicone prepolymers co-react in the thermoplastic matrix during melt extrusion and injection molding to form a partially crosslinked network within the thermoplastic matrix. [Pg.1109]

Before irradiating a polymer, two kinds of additives could be incorporated. The first kind is that of radical scavengers (like hydroquinone, and more generally aromatic additives). Chen et al. studied the effect of four different aromatic additives on the radiation resistance of 60/40 styrene-ethylene/ butylene-styrene copolymer (SEBS)-PS blends. Considering the changes in mechanical properties, thermal stability and volume resistivity, pyrene was found the most efficient additive and diphenylacetylene (DPA) the worst. The authors concluded that the best protection effect could be attributed to... [Pg.266]

In some cases, lack of noticeable influence of electron beam radiation on the values of tensile and Charpy impact strengths of 24-23-21-15-17 LDPE-HDPE-PP-PS-PET blends (based on recycled polymers) compatibilized with 1% trimethylol propane trimethylacrylate (TMPTMA) were found. Zenkiewicz et al. ° explained this lack of influence by the protective action of aromatic rings of PS and PET that hindered cross-linking. In the same article, the addition of 10% of styrene-ethylene/butylene-styrene elastomer grafted with maleic anhydride (SEBS-g-MA) led to the great increase of both tensile and Charpy impact strengths.

The three major types of TPEs are block copolymers such as SEES (styrene-ethylene-butylene-styrene block copolymer) (Kraton by Kraton Polymer), polyether— polyester (Hytrel by DuPont), rubber/plasticblends (900 series Sumitomo Chemical), and dynamically vulcanized rubber/plastic alloys (Innoprene by Kumho Polychem, Santo prene by Exxon-Mobil, Sarlink by DSM, Unipene byTeknor Apex). Figure 3.28 shows the cost versus general performance comparison for different TPEs [31]. [Pg.152]

Kraton TPEs are usually SBS, SEBS, and SIS, as are SEP (styrene ethylene/propylene) and SEB (styrene ethylene/butylene). The polymers can be precisely controlled during polymerization to meet property requirements for a given application. ... [Pg.192]
