Epoxidation of partially hydrogenated styrene‐butadiene block copolymers using peracetic acid in a cyclohexane/water heterogeneous system

Synthesis, Characterization, and Interaction Strengths of Difluorocarbene-Modified Polystyrene−Polyisoprene Block Copolymers

“…The domain spacing is determined by the balance between the unfavorable interfacial energy and the entropic penalty due to the deformation of the polymer coils. 3 Mean-field theory provides an explicit prediction for D in lamellar samples: 32 Equation 7 is strictly applicable only in the strongsegregation regime (χN g 100), whereas the PSPI (10,8) series at 110 °C falls in the intermediate segregation regime. Nevertheless, eq 8 should provide a reasonable and internally consistent estimate of χ for the following reasons.…”

“…In frequency sweeps at 100 °C, the dynamic moduli (G′ and G′′) each scale with approximately the 1 / 2 power with frequency ω as ω f 0, characteristic of a lamellar microstructure. 2 From SAXS measurements at 110 °C, we determined D of the modified PSPI (10,8) series by use of eq 1 (Table 2). These values along with the D values from the modified PSPI(34, 27) series, normalized by that of the corresponding precursor PSPI (D o ), are plotted versus the molar percentage of modification in Figure 5.…”

Biobased Epoxy Matrix from Diglycidyl Ether of Bisphenol A and Epoxidized Corn Oil, Cross-Linked with Diels–Alder Adduct of Levopimaric Acid with Acrylic Acid

“…The molar ratio of oil double bonds/acetic acid/hydrogen peroxide was 1/0.5/2. Cyclohexane was used as solvent with the aim to minimize the opening of the epoxy ring and facilitate the epoxidation reaction because peracetic acid is soluble both in cyclohexane and aqueous phases. − …”

Epoxidation of Styrene/Butadiene Star Block Copolymer by Different Methods and Characterization of the Blends with Epoxy Resin

“…The SBS block copolymer was epoxidized by following the procedures discussed elsewhere . One gram of SBS was dissolved in 25 ml of dichloromethane and taken in three necked flask with magnetic stirrer.…”
