Hyperbranched polymers possess unique characteristics such as low viscosity, high solubility in organic solvents and a high degree of functionality at the terminal position. However, hyperbranched polymers also possess weak mechanical properties. In

Hyperbranched poly(ether sulfone) polymers having sulfonyl chloride end-groups is blended at up to 30 w% with linear poly(ether ether ether sulfone)s and a two-phase system is generated via spinodal decomposition upon drying from a DMAc solution. Con

Hyperbranched polysiloxysilane (HBPS) with terminal vinyl groups P1 was synthesized by self-condensation reaction using platinum-catalyzed hydrosilylation of 1,1,3,5,5-pentamethyl-1,5-divinyltrisiloxane. A number-average molecular weight (Mn) was 540

Hyperbranched poly(ether sulfone) was prepared in the presence of an oligomeric linear poly(ether sulfone) to generate multiblock hyperbranched-linear (LxHB) copolymers. The LxHB copolymers were prepared in a two-step, one-pot synthesis by first poly

The preparation of a new hydantoin-containing polyurethane surface modifier has been enabled by the development of a hydantoin-oxetane monomer that co-polymerizes to polyoxetane telechelics by ring-opening polymerization. After solution blending the

We report the synthesis of a new oxetane monomer 5,5-dimethyl-3-(2-((3-methyloxetan-3-yl)methoxy)ethyl)-imidazolidine-2,4-dione (Hy4Ox, 1), an oxetane with a hydantoin-containing moiety in the 3-position. This hydantoin–oxetane monomer is stable to

Oxidation of the surface of syndiotactic 1,2-polybutadiene (PBD) films with aqueous KMnO4/K2CO3 at room temperature produced PBD-ox, containing a range of oxidized functionality. When heated against water, the surface of PBD-ox became more hydrophobi
