Abstract: A process for preparing solvent-free aqueous polyurethane dispersion modified with acrylic grafting is divided into four steps. The first step is a reaction of a diisocyanate with a polyol to prepare a prepolymer; the second step involves diluting the prepolymer with an acrylate monomer and adding a sulfonate-based chain extender to react; the third step involves adding deionized water and a water-soluble diamine-based chain extender to obtain a solvent-free sulfonate-based aqueous polyurethane dispersion; and the fourth step involves letting the aqueous polyurethane become modified with acrylic grafting. The resulting aqueous polyurethane has excellent mechanical strength, heat resistance and water resistance.

Abstract: In neural-network-based approaches to sequence modeling, an output sequence may be modeled via segmentations, the probability of the output sequence being constructed as a sum of products of output-segment probabilities, taken over all valid output-sequence segmentations. A set of artificial neural networks may model the distribution of the output-sequence probability with a recurrent neural network modeling the distributions of the individual output-segment probabilities, optionally in conjunction with a second recurrent neural network modeling concatenations of output segments. In various embodiments, this approach is applied to neural phrase-based machine translation.
