The Effects of Preferential Solvents on the Phase Separation Morphology of Styrene-Ethylene Oxide B the morphology of block copolymers of poly(ethylene oxide) (PEO) and polystyrene (PS) as well as poly (propylene oxide) and PS, in concentrated solutions using small angle x-ray techniques. By varying both concentration and solvent type, they were able to create several interesting gel structures.

This behavior is explained by the fact that the polymers possess a three-dimensional network built up by intermolecular association (cr

Mechanical and Optical Properties of Block Polymers II. Polyether Urethanes,tion. Typically, an elastomeric block polymer is built of alternate segments of a glassy or rigid polymer and a rubbery polymer resulting in a material which is more flexible than the pure rigid polymer, but possessing a higher modulus than the pure rubbery segment. The intelligent design of block p

Structure and Properties of Alternating Block Polymers of Dimethylsiloxane and Bisphenol-A Carbonature exists on the scale of 10. A ca.. Many physical properties of these systems are well known to differfrom those of their random-copolymerized counterparts because of this structure. Block polymers of dimethylsiloxane and bisphenol-A carbonate have been synthesized by H. A. Vaughn.which exhibit ph

(For example, this addition to a SBS polymer of 30 wt. % styrene to give an overall composition of 40 wt. % styrene increased the modulus at an extension ratio of 5 from 23 to 44 kg. /cm.. at a strain rate of 31.5 min..)
