Title: New polyether-polycarbonate block copolymers - derived from 1,1-bis-(4-hydroxyphenyl)-cycloalkane(s) and polyether-glycol(s) by reaction with phosgene, etc.
Inventor: DHEIN ROLF DIPL CHEM DR
IPC: B01D71/50
Filed: 1992-01-09
Abstract: The use of diphenols of formula (I) for the prodn. of polyetherpolycarbonate block copolymers (II) is claimed. In (I), R3, R4 = H or Me; R5, R6 = H or 1-6C alkyl (can be different for each X); X = carbon; m = 4-7. Also claimed is prodn. of (II) from aromatic diphenols and polyethylene oxide glycols (PEG) and/or polypropylene oxide glycols (PPG) and/or polyethylene oxide/polypropylene oxide glycols (PEG/PPG), with Tg above 100 deg.C in the polycarbonate block, by the normal methods, opt. using chain cleavage agents and branching agents; at least 10 mole% of the total amt. of diphenols consists of (I). Also claimed are mixts. (III) contg. 10-95 wt.% (II) and 90-5 wt.% other film-forming thermoplastics (IV), and a process for producing mixts. (III) by mixing the components in the melt or in soln. and isolating the prod. by known methods. USE/ADVANTAGE - (II) and (III) are useful for the prodn. of membranes (claimed). Also claimed are membranes produced from (II) and (III), and the use of such membranes for dialysis. (II) contain hard (polycarbonate) segments with high Tg (pref. above 150 deg.C), and are therefore more temp. resistant than prior-art block copolymers; this prevents the individual components bonding together at elevated temp., without adversely affecting mol.wt. or transparency. Prods. contg. (II) (tubing, films, membranes, etc.) thus have better properties w.r.t. storage, transport and sterilisation.

Patent DE-4222369-A1 (DE)
Inventor: LAUER LEONHARD DR
IPC: B01D21/01
Filed: 1992-07-08
Abstract: In a method for operating a sewage treatment plant, the electrolytic conductivity of the feed effluent (waste water) and the flow rate thereof are continuously measured and used to form a parameter (S) determining the rate of a precipitant to be added. Individual measurements of the phosphate concentration are carried out in this case. The load signal is corrected in dependence on these individual measurements. An apparatus for injecting the phosphate precipitant has a precipitant pump (12) and an actuating apparatus (14) determining the throughput. In addition, there is a conductivity metering apparatus (19) in the feed effluent, a flow meter (16) and a control apparatus (18) which continuously calculates a parameter (S) for the actuating apparatus (14) from conductivity (LF), flow rate (Q) and, if necessary, correction values. In this manner, on-line operation is possible with precipitant metering operating almost precisely. <IMAGE>
