The spatial distribution of the terminal groups of poly(amido amine) dendrimers have been determined experimentally by small-angle neutron scattering with deuterium labeling and scattering contrast variation. The radius of gyration of deuterated term

A series of Starburst ™ polyamidoamine (PAMAM) dendrimers, built from a tetrafunctional ethylenediamine (EDA) core, generations 1 to 10 (G1–G10), and covering a wide range of charge state distributions (i.e. from m / z ∼ 500 to m / z ∼ 15 000

Vitamin A and its derivatives (commonly termed retinoids) are widely used in topical anti-aging products. Certain retinoids such as retinol and its esters are available without a prescription, while others such as tretinoin are available only via pre

The step-growth polymerization of the AB 2 blocked isocyanate monomer 3,5-bis((benzoxycarbonyl)imino)benzyl alcohol at a monomer concentration of 1 M results in the formation of a hyperbranched polyurethane with M w = 94 000. When the monomer concent

The accelerated synthesis of regular dendritic poly (ether-urethane) macromolecules through growth of two generations in a single synthetic operation has been explored. This procedure requires the use of two AB2 monomers such as 3,5-diisocyanatobenzy
