摘要： Cement compositions comprising a modified styrenic block copolymers and methods for making/using the same are disclosed. The modified styrenic block copolymer has at least one monoalkenyl arene polymer block A, at least one conjugated diene polymer block B, and at least an epoxy functional group or derivative thereof. The modified styrenic block copolymer has a degree of epoxidation of up to 10-90%. The cement composition can be used in subterranean applications, as well as in building and construction materials. The modified styrenic block copolymers swell upon contact water or other aqueous fluids to seal cracks in the cement.

摘要： The disclosure relates to an impact modified polyarylene sulfide composition containing epoxy functionalized styrenic block copolymer (e-SBC), for improved impact resistance with minimal impact on processability, wherein e-SBC is an epoxy functionalized unhydrogenated styrenic block copolymer (e-USBC), or an epoxy functionalized partially hydrogenated styrenic block copolymer (e-pHSBC), or an epoxy functionalized hydrogenated styrenic block copolymer (e-HSBC). The improved PPS composition can be used for making electronic components such as, but certainly not limited to, connectors, bobbins, coils, relays, etc.

摘要： The disclosure relates to a cured composition obtained by curing a curable polymer composition comprising: (a) at least one hydroxyl group containing compound selected from diols, triols, tetraols, polyols, polymeric polyols, and mixtures thereof; and (b) a sulfonated styrenic block copolymer (SSBC) containing a block A, a block B, and a block D. Each block A and D is resistant to sulfonation and the block B is susceptible to sulfonation having a degree of sulfonation of >10 mole %. The curable polymer composition is cured by treating with radiation or thermal energy for improved mechanical properties. The cured composition can be used as a membrane in water purification applications.

摘要： A polyelectrolyte composition is disclosed comprising (a) a polyionic multiblock polymer (PILSBC) comprising a styrenic block copolymer (SBC) precursor having at least a quaternary ammonium salt; (b) a cross-linking agent comprising a compound having at least two amino groups; (c) a lithium salt; and (d) an ionic liquid. The SBC precursor comprises at least a block D derived from a substituted vinyl aromatic monomer; a block A derived from a vinyl aromatic monomer; and optionally a block B derived from a conjugated diene monomer. The polyelectrolyte composition has a mol ratio of the ionic liquid to the quaternary ammonium salt of 0.1:1-1:1. The polyelectrolyte composition provides improved ionic conductivity and electrochemical properties, and can be used in batteries, e.g., a Li-ion battery.
