Textile size

Textile size. Jelinek, Milan; Smid, Josef (Czech. ). Czech. CS 163884 15 Jul 1976,4 pp. (Unavailable). (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: D06M011-00. APPLICATION: CS 71-7780 5 Nov 1971. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Olefinic aldehyde polymers in combination with starch gave sizes which were chem. inactive, did not discolor the textile, had high adhesion to textiles and could be removed by washing. Thus, polyacrolein [25068-14-8] (catalyzed by K2S2O8 and AgNO3) was added portionwise at 20-40.degree. to an aq. Na2S2O5 soln. under nitrogen, stirred 4 h to give a viscous soln., homogenized with potato or corn starch [9005-25-8] and H2O to give stable clear sizes useful for polyester fabrics or as lubricant for glass fibers.

Agarose-polymeric microsphere beads: specific new adsorbents for hemoperfusion

Agarose-polymeric microsphere beads: specific new adsorbents for hemoperfusion. Margel, Shlomo (Plast. Res. Dep., Weizmann Inst. Sci., Rehovot, Israel).Chemicals with cas numbers 115-09-3 and 7487-94-7 also play role. React. Polym., Ion Exch., Sorbents, 1(4), 241-50 (English) 1983. CODEN: RPISDH. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 4, 15 Uniform agarose [9012-36-6]-polymeric microsphere beads of 1 mm diam. were synthesized by encapsulating appropriate polymeric microspheres in an agarose matrix. The potential use of these beads for hemoperfusion was demonstrated. Agarose provides the high porosity and the biocompatibility of the beads; the encapsulated microspheres are used for the removal of harmful substances from the circulatory system. Two types of polymeric microspheres were prepd.: (a) polymercaptal microspheres of 0.8 mm av. diam.; (b) polyacrolein [25068-14-8] microspheres of 0.2 mm av. diam. Agarose-polymercaptal microsphere beads were designed for the removal of heavy metals by hemoperfusion. As a model, the detoxification of mercury compds. was studied. Agarose-polyacrolein microsphere beads were designed for the removal of antibodies by hemoperfusion, esp. in autoimmune diseases. As a model, the removal of anti-BSA from immunized animals was studied. .
