Adding knowledge to the design of safer hydrophobically modified poly(acrylic) acids: an ecotoxicological approach.

ABSTRACT: The architecture of hydrophobically modified polymers can be tailored to produce variants with different levels of functionality. This allows industry to apply rational design methods for the development of more environmentally friendly materials. In the present work, the ecotoxicity of six variants of hydrophobically modified poly(acrylic) acids (HMPAA), obtained by changing the crosslinked conformation, insertion position, and length of the hydrophobic groups, was assessed for the (i) bioluminescence production of Aliivibrio fischeri; (ii) population growth rate of Raphidocelis subcapitata and Chlorella vulgaris; (iii) mortality of Brachionus calyciflorus; (iv) feeding inhibition, somatic growth rate, reproduction, and mortality of Daphnia magna; and (iv) mortality and somatic growth rat
