Block copolymers, having the configuration ethylene sulphide-isoprene-styrene or ethylene sulphide-isoprene ethylene sulphide, have been characterized to define the structure of the ethylene sulphide moiety. It is concluded that ethylene sulphide-isoprene-styrene block copolymers exist in solution a

## Abstract This work compared the elastomeric properties of two low‐crystallinity ethylene–octene copolymers. One was a block copolymer with lamellar crystals and the other was a random copolymer with fringed micellar crystals. The comparison of the stress–strain behavior at 23°C revealed that the

## Abstract **Summary:** An ordered nanoporous monolith was prepared from a poly(isoprene‐__b__‐dimethylsiloxane) (PI‐PDMS) hexagonally packed cylinder precursor. The PDMS cylinders were macroscopically aligned, the PI was crosslinked with dicumyl peroxide, and the PDMS was removed using tetrabutyl

## Abstract Butadiene–ε‐caprolactam block polymers containing a high proporation of 1,2 units in the butadiene‐segments were synthesized and physical properties were measured on the cured copolymers. Flexural strength and impact resistance both increase regularly with increasing ε‐caprolactam conte
