“…206 They observed higher Young's modulus and tensile strength values for 4,4-dicyclohexylmethane diisocyanate based polymers than for tetramethylxylene diisocyanate, which was related to a higher degree of phase separation and increased hydrogen bonding within the PU part of the polymer. Wang et al 201,207 compared PU/acrylic hybrids synthesized via miniemulsion polymerization and seeded emulsion polymerization. An external emulsifier was used in the miniemulsion polymerization while in the seeded emulsion polymerization method, stabilization was provided by the DMPA contained in the PU.…”

Polyurethane (PU)/acrylic hybrid dispersions are an important class of polymeric dispersions that are produced on an industrial scale. In this review, we detail the design and synthesis of PU/acrylic dispersions, with a particular focus on how the structure of the hybrid can be tuned toward commercial applications. After a brief introduction, we describe the building blocks used in each polymer and their role in the synthesis/application of the final dispersion. Subsequently, we discuss the range of procedures that have been developed for the synthesis of such hybrids and how the structure of the hybrids influences the physical properties of films cast from the dispersion. Finally, we highlight commercial applications of PU/acrylic hybrids, with a focus on potential future developments.

“…42,43 These mixtures show a good storage stability without premature crosslinking, and synergistic properties have been reported, including flexibility at low temperature and a good abrasion resistance. 44 More than one population of polymers within the same particle 45 Another distinct type of heterogeneity is the situation in which each individual particle in an aqueous polymer dispersion contains more than one polymer. In the following sections, addition polymer/addition polymer combinations and addition polymer/condensation polymer combinations are discussed.…”

An overview is presented of the progress in understanding polymer heterogeneity over the last 20 years and how this has contributed to the improvement of coatings. Solvent-based polymers are homogeneous in nature, since all polymeric materials tend to be dissolved in the same solvent mixture. This is different for most waterborne polymers, which tend to be present in a compartmentalized way. Most polymeric materials are present in particles, which are separated by the continuous aqueous phase. This gives excellent opportunities to create particle morphologies that form the basis for the film morphology after drying of the coating. This article gives an overview of the various types of heterogeneity which are accessible in waterborne polymers and will show how heterogeneity in the polymer can contribute to the solution of several persistent problems of the coating industry.
