1. Isquith, A. J., Abbott, E. A., and Walters, P. A., US Patent 3,730,701, May 1, 1973, discloses the use of (CH3O)3Si(CH2)3N(CH3)2R+Cl− or Br− in solution to flocculate algae with R = alkyl group with 11 to 22 C atoms.
2. Abbott, E. A., Isquith, A. J., and Walters, P. A., US Patent 3,817,739, June 18, 1974, discloses a method of inhibiting the growth of algae on any solid, and the US Patent 3,865,728, February 11, 1975, on fibers. The solids and fibers had polysiloxane resins deposited upon them, which deposits can be obtained by hydrolysis of the compounds claimed in Ref. (1a).
3. Abbott, E. A., and Isquith, A. J., US Patent 3,794,736, February 26, 1974, claims a method of inhibiting the growth of bacteria and fungi by contacting said organisms with almost any organosilicon-substituted amine or amine salt in solution or affixed to a substrate, especially in the form of a co-polysiloxane containing copolymer units which do not contain amine groups; US Patent 3,860,709, January 14, 1975, almost the same, restricted to homopolymers.
