Structural evolution of an ABA poly(styrene‐b‐isoprene) …

The structural evolution with temperature of an anionically synthesized ABA poly(styrene‐b‐isoprene) (SIS) lamellar block copolymer (total molecular weight 45,000; isoprene content 38% by weight) was studied by melt‐rheological measurements, electron microscopy, and x‐ray and light diffraction.

Micellar transformations of poly(styrene-b-isoprene) block …

While micelles formed in DMF were stable and no morphological changes occurred as a function of the temperature, transformations from cylinder-like micelles to vesicles-like objects were observed in both decane and heptane above 60 °C for the linear PS-b-PI copolymer. The transition occurred through intermediate steps, where the coexistence ...

Styrene-Isoprene-Styrene Rubber Properties and Applications. Styrene-isoprene block copolymers (SIS) are large volume, low priced commercial thermoplastic elastomers (TPE) which are produced by living ionic copolymerization by sequentially introducing styrene, 2-methyl-1,3-butadiene (isoprene), and styrene into the reactor. The styrene content typically varies …

diblock copolymer liquids based on the solution of liquid-state integral equations. To our knowledge, few studies have looked into the phase structures of specific diblock copoly-mers. The morphologies and mechanical properties of poly styrene-b-isoprene PS-b-PI diblock copolymers have recently been studied by Soto-Figueroa et al.22,32–34 Ortiz

SIS - polymerdatabase

Styrene-isoprene block copolymers ( SIS) are large volume, low priced commercial thermoplastic elastomers (TPE) which are produced by living ionic copolymerization by sequentially introducing styrene, 2-methyl-1,3-butadiene (isoprene), and styrene into the reactor. The styrene content typically varies between 15 and 40 percent.

copolymer solutions are subjected to strong flows. Gast and coworkers investigated SI diblock copolymers in decane with either an fcc or bcc structure using in situ small angle neutron scattering (SANS) (McConnell et al., 1995). aVrious steady shear rates were applied with a Cou-ette cell. For the fcc phase, the polycrystallinity at low

In this study, the kinetics of intercalation of a series of poly(styrene‐b‐isoprene) block copolymers into a layered silicate were examined via X‐ray diffraction. Intercalation was observed even when the copolymer was in the ordered state, with no discontinuity around the order–disorder transition of the copolymer.
