TL;DR: In this article, the effect of additive concentration in the casting solution on physico-chemical properties of home-made membranes was studied, where tetrahydrofuran as solvent and cation exchange resin powder as functional groups agent were used to help in appropriate dispersion of particles in the membranes matrix.

TL;DR: In this paper, the authors used carbon black filler with three different doses (5, 10, and 20 wt % of filler) to form three different filled and crosslinked membranes, i.e., SBR5, SBR10, and SBR20.
Abstract: Styrene butadiene rubber (SBR) was efficiently cured (crosslinked) by using sulfur to accelerator ratio less than unity. This cured SBR was further compounded with carbon black filler (grade N330) with three different doses i.e., 5, 10, and 20 wt % of filler to form three different filled and crosslinked membranes, i.e., SBR5, SBR10, and SBR20. These filled rubber membranes and one unfilled but efficiently cured membrane, i.e. SBR0, were used for pervaporative removal of pyridine from its mixtures with water. The filled membranes were found to show better selectivity and mechanical properties but lower flux than the unfilled membrane. All of these membranes showed reasonably good range of flux and pyridine selectivity. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

Abstract: There is disclosed a pneumatic tire having a rubber component comprising a sulfur cured rubber composition composed of, based on 100 parts by weight of rubber (phr): (a) 99 to 50 parts by weight of a first rubber containing olefinic unsaturation; and (b) 1 to 50 parts by weight of a second rubber which is different from said first rubber and which is an elastomeric block copolymer of (1) from 15 to 65 percent by weight, based on the total block copolymer, of butadiene, and (2) from 35 to 85 percent by weight, based on the total block copolymer, of styrene, which block copolymer has: (a) at least two blocks A which have polymerized units of styrene, a glass transition temperature Tg above 25° C. and forms a rigid phase, and (b) at least one elastomeric block which is composed of about 25 to 70 percent by weight of butadiene and 75 to 30 percent by weight of styrene, and which has polymerized B/A units of styrene and butadiene in a random structure; a glass transition temperature Tg from −50° C. to 25° C., and is located between two blocks A and forms a flexible phase, and the amount of the rigid phase accounts for 5 to 40 percent by volume.
