Web4 de abr. de 2024 · We studied the reactivity and versatility of the new initiator through the polymerization of propylene oxide, butylene oxide, epichlorohydrin, and allyl glycidyl ether into homopolymer, statistical copolymer, and block copolymer architectures with heterobifunctional end-groups consisting of dibenzylamine and hydroxyl functionalities. WebThe opening and closing of the water-loosing stomata is regulated by guard cells that, in turn, are regulated by uptake of potassium ions. As guard cells change shape, stomata open and close. Greater bowing of the guard cells during turgor increases the size of the stoma opening.
