Ecotoxicological Properties of Tulipalin A-Based Superabsorbents versus Conventional Superabsorbent Hydrogels

Abstract

The Phytotoxicological Aspects of a Novel Superabsorbent/Hydrogels: poly(acrylamide-co-sodium 4-hydroxy-2-methylenebutanoate), prepared from renewable monomer Tulipalin A, on the growth and development of monocotyledonous Avena sativa and dicotyledonous Raphanus sativus, was investigated and compared with the effect of borate-crosslinked poly(vinyl alcohol), poly(acrylamide), and poly(acrylamide-co-sodium acrylate) conventional hydrogels. Tulipalin A-based superabsorbent hydrogels revealed superior properties in terms of the combination of the tested properties. The results confirmed excellent suitability of Tulipalin A-based hydrogels for application as reservoirs of water during plant stress condition. Values of fresh matter (yield) and shoot height of the examined plants growing in soil amended with these hydrogels were ca 10% higher than those of plants growing in soil without hydrogels. Reference borate-crosslinked PVA hydrogels (containing increasing amount of borax cross-linker) revealed harmful effect on plants. The negative effect was observed on most of the investigated properties, increasing with content of the hydrogel in soil and concentration of the borax in it.

Functional Polymers and Polymeric Materials From Renewable Alpha-Unsaturated Gamma-Butyrolactones

“…Therefore, another big class of application of poly(amidoamine)s are in medicine or biotechnology (Hartmann et al, 2006;Magnaghi et al, 2011;Martello et al, 2014;Ndamase et al, 2018). In addition, MBL-based poly(amidoamines) Kollár et al, 2016Kollár et al, , 2019Luk et al, 2017;Rychter et al, 2019 Linear or starlike P(MBL-co-CL)…”

“…In addition, effect of various stimuli, such as pH, ionic strength, and temperature were investigated to prove stimuliresponsive behavior of the hydrogels . For agricultural purposes, the phytotoxic properties of SHMB/AM hydrogels were tested and compared with conventional and commonly used hydrogels (Rychter et al, 2019). Among tested materials, SHMB-based hydrogels were found to be non-toxic with even slightly positive effect on growth of green parts of plants.…”

The Effect of New Thiophene-Derived Diphenyl Aminophosphonates on Growth of Terrestrial Plants

“…The plant growth test of diphenyl amino(2-thienyl)methylphosphonates 1 – 6 was performed in laboratory conditions following the OECD 208 Guideline Terrestrial Plants Growth Test [25]. Inhibition ratio (IR) was calculated according to the method reported by Wang et al [26], as well as Pawłowska and Biczak [27]. This method has already been described by other authors [23,24,28,29,30,31], and the detailed procedure is fully described in the Supplementary Materials Part 2.…”

Production and Polymerization of Biobased Acrylates and Analogs

“…The authors recently further studied the reaction conditions of this synthesis, [ 407 ] as well as the ecotoxicological properties of the hydrogels obtained for potential cell culture applications. [ 408 ] Hutchinson and co‐workers developed a similar material from γ‐MMBL. [ 409 ] A final original example of polymerization of MBL was published by Agarwal and Kumar in 2011.…”
