    Abstract: New cpds. (I) are of formula (I) where n = 1-70; R1, R2 = H, 1-6C alkyl, 7-12C aralkyl, aryl, or carbon ester, or R1 with R2 = tetra- to hexa-methylene gp. or opt. substd. fluorene-typering of specified formula; X, Y = O, S, or NR7 where R7 = H, 1-8C alkyl, or 7-12C aralkyl; M = (II) where R3, R4, R5, R6 = alkyl, or R3 with R4, and R5 with R6, form with attached C atom, 5 or 6-membered ring, R8 = H or alkyl, or with attached C atom, denotes =C:O, and R9 = H or further bond to spiro-linked bridge member -B- (A then denoting direct bond); each D= -(CH2)m-, where m = 1-20, or, if residue M is joined with A through N atom, can also be a direct bond, at least one gp. -M-D being present, with M in this gp. being linked to D via N atom; each A = opt. substd. N, COOH, CO, SO2, SO2NH2, or direct bond; B = bridge member or direct bond; C has 20 meanings, e.g., H, acyl, Cl, OH, NH2, or gp. of formula (III) wherein each R13 = H or CH2OR14 where R14 = H or 1-22C alkyl opt. interrupted by ether O, N or S, or the R13 together denote -CH2-N (R15)-CH2 where R15 has 28 meanings, e.g., 1-22C alkyl. Alternatively, -M-A-B-A-C-represents gp. of formula (IV)-(VI) where R16-R20 together have over 50 meanings. Acid addn. salts and hydrates of (I) are also claimed. Polyalkylpiperidines of specified general formulae, as intermediates for (I), and their acid addn. salts and hydrates, are also claimed.

    Abstract: Polycondensates (I) with repeating units of formula -(-O-Pc(Si)O-D)n- in the main chain are claimed; Pc(Si) = phthalocyanine residue with a central Si atom; n = 5 or above; D = (D1); 3-5 ring arylene, opt. substd. with Cl, F or 1-4C alkyl; (D2); 1-2 ring arylene, opt. substd. with Cl, F, NH2 or 1-4C alkyl; (D3); 5- or 6-membered N-, O- or S-heterocycle with a conjugated pi-electron system; (D4); -CO-R1-CO- (with R1 = 1-18C alkylene or 6-12C arylene); or (D5); a gp. of formula (I) (with X = -O-, -CO-, -CMe2-, -S-, -SO2- or -CO-C6H4-q(R4)q-CO-; R2, R3, R4 = 1-4C alkyl or Hal; k, m, q = 0 or 1-4; p = 0 or 1). USE/ADVANTAGE - (I) are useful for the prodn. of moulded prods. (claimed). The invention provides polycondensates with new, quasi-aromatic, axially-centred macrocyclic gps. (I) have the advantageous properties of the polymer type on which they are based (polycarbonate, polyester, polyether or polysulphone), and are useful for the prodn. of fibres, film or antistatic coating materials, and as catalysts, sensors, and electrodes for batteries and photovoltaic cells.
