In this work, the synthesis of a series of biobased acrylic latexes is discussed, which are capable of manipulating the mechanical properties of films cast from natural rubber latex in order to expand the range of potential applications. On the one hand, a series of isobornyl acrylate-rich, hydroplasticizable latexes containing methacrylic acid are synthesized. Blends of the neutralized form of these acrylic latexes with natural rubber latex lead to a phase-separated film structure containing glassy domains of the poly(isobornyl acrylate)-rich polymer and softer domains of the natural rubber latex. This film structure results in an increase of the Young's modulus of several orders of magnitude, which makes them of interest for coatings. On the other hand, when similar non-hydroplasticizable poly(isobornyl acrylate) latexes are synthesized but with much lower molar mass, the relatively high T<sub>g</sub> acrylic component and the low T<sub>g</sub> natural rubber latex are miscible, leading to a tackified system that displayed reasonable adhesive properties.

The effects of LDI on the reactive mechanism, thermodynamic behavior, mechanical properties, and phase morphology of the blends are thoroughly investigated.

Thermodynamics behaviors show that LDI reduces the crystallization rate and crystallinity of the blends.
