“…In the past decades, polyacrylate emulsions-based PSAs have been widely used in building, electron and wiring, automobile, packing, and daily life, because of some advantages such as freepollution, low cost, simple process and easy controllable viscosity, and so forth [38,39,40,41]. Hydrogenated rosin (HR)/polyacrylate composite mini emulsions-based pressure sensitive adhesives are synthesised by in situ mini emulsion polymerisation method [42].…”

Rosin is the non-volatile exudate of pine resin with hydrophobic characteristics that are widely used and modified as a precursor for many industrial applications such as paints, inks and adhesives. The review paper discusses the rosin, its nature, processing, production material development for green science. The composite materials have been designed and tailored with respect to desired applications to offer a potential replacement of petrochemical use. Rosin consists of different resin acids that can undergo isomerisation at elevated temperatures and interchange its form, which, can be used as a rigid building block to manipulate their mechanical properties and crystallisation behaviours. Modified rosin epoxy binders have been recognised as materials with resistance to a wide variety of chemical conditions that can be used to fabricate a variety of reinforced constructions. Rosin has been employed in foam making in addition to composite material, depicting its ability as a crosslinker.

“…[1][2][3][4] However, some technical problems still need to be solved with further effort, for example, the usage of the surfactant and the monomer containing carboxyl groups lead to the latex films' low resistance to water, the adhesion properties of polyacrylate emulsions especially for the nonpolar materials such as polyolefin are relatively poor. [5][6][7] Therefore, the application of the polyacrylate emulsions is restrained at a certain degree.…”

Hydrogenated rosin/polyacrylate composite miniemulsions-based pressure sensitive adhesives were synthesized by in situ miniemulsion polymerization method. The effect of HR amount on the monomer conversion rate, particle size and its polydispersity, coagulum rate, Zeta potential, and stability of the composite miniemulsions were studied, the effect of HR and crosslinker amount on the adhesion properties of the composite latex films were also investigated, and the composites were characterized by differential scanning calorimetry (DSC) and gel permeation chromatograph. The results showed that with HR amount increasing, the monomer conversion rate decreased, and the absolute value of Zeta potential and the molecular weight of the sol in the composite latex films also decreased, while the particle size and its polydispersity were almost unaffected. DSC analysis indicated that HR had relative good compatibility with polyacrylate. However, excess HR amount led to the decrease of the centrifugal stability and storage stability of the composite miniemulsions. Furthermore, with HR amount increasing, the ball tack of the latex films increased gradually, 180 o peel strength first increased and then decreased, and holding force decreased constantly. When HR amount exceeded 10 wt%, the failure style changed from interface failure to cohesion failure. The crosslinker CX-100 was helpful for the improvement of 180 o peel strength and holding force. When HR and CX-100 amount were 10 and 0.6 wt%, the ball tack, 180 o peel strength, and holding force were 9 #, 8.9 N/25 mm, and 178 h, respectively.

“…PUA emulsion, as a modification of PU dispersion, has good mechanical properties, film-forming properties, cold resistance, water resistance and weather resistance, and good gloss after film formation. [1][2][3] PUA emulsion can combine the advantages of PU and PA (polyacrylate) emulsions, [4][5][6][7][8][9] and well solve the disadvantages of slow drying rate and weak adhesion of water-based inks on flexible packaging film substrates. [10][11][12][13][14][15] Soap free emulsion polymerization is performed by using ionic radical initiators to synthesize polymer particles in water.…”

Waterborne modified polyurethane (PU) dispersions with different macromolecular diols as soft segments were prepared by the self-emulsifying method, and then compounded with the acrylate monomers, the polyurethaneacrylate composite emulsion (PUA) with the core-shell structure was prepared by emulsifier free emulsion polymerization. The effects of the type and ratio of macromolecular diols in the soft segment on the particle size and distribution, rheological properties, adhesion, water absorption and thermal properties of the PUA emulsion were studied. The results showed that the particle size of PUA decreased, and the shear resistance and heat resistance of PUA were enhanced with the addition of polypropylene glycol.According to the water absorption rate of PUA emulsion, it was found that adding poly-1,4-butanediol adipate glycol and poly(caprolactone) diol with more hydrophobic groups could improve the water resistance of PUA dry film, and the minimum water absorption value was 0.68%.
