摘要:
The disclosure provides, in various embodiments, a method for fractionating a polyalkylene, and the fractionated polyalkylene produced thereby. The method includes, for example, separating, from a starting polyalkylene, a first portion of a polyalkylene having a Mw less than the Mw of the starting polyalkylene. Also included are bichromal balls or beads comprising the fractionated polyalkylene, such as the first portion of a polyalkylene.

Disclosed is a phase change carbon black ink composition comprising 1) a low polarity ink carrier comprising (A) a low polarity wax, optionally (B) an ester-terminated polyamide, (2) a dispersant, and (3) a carbon black colorant. The ink can be resistant to substantial aggregation and settling of the carbon black colorant in the melt and up to about the jetting temperature of the ink even when exposed to freeze thaw cycles.

Disclosed is a phase change black ink composition comprising (1) a low polarity ink carrier comprising (A) an ester-terminated polyamide, (B) a Guerbet alcohol or a Guerbet alcohol mixture including at least one linear alcohol, and (C) a low polarity wax, and (2) a black colorant. The ink carrier can also include a dispersant. The ink is resistant to aggregation and settling of the black colorant when a standby-mode printer temperature for the ink is not more than about the gel temperature of the ink.

Disclosed is an ink carrier comprising (A) an antioxidant mixture comprising (a) a hindered phenol antioxidant, and (b) a hindered amine antioxidant, (B) a polyalkylene wax, (C) a functional wax, and (D) an ester-terminated amide. The low polarity ink carrier is substantially resistant to phase separation, has excellent thermal stability, resists autocatalytic degradation of the ink composition and a substantial color shift upon standing, and provides enhanced humidity resistance. This ink carrier can be combined with a colorant to produce an ink composition.
