Benzyl methacrylate

Description

The cyclic methacrylate monomer benzyl methacrylate (BzMA) was evaluated as an alternative to traditional methyl methacrylate (MMA) as a hard monomer in the application of an acrylate latex pressure-sensitive adhesive (PSA). BzMA is widely used in nanoimprinting lithography, paint applications, inkjet inks, transparent adhesives, orthodontic adhesive compositions, and stationary phases in liquid chromatography[1].

Chemical properties

Colorless oily liquid. Very slightly soluble in water, soluble in alcohol and oils. Soft, warm, herbaceous-rosy odor of moderate tenacity.

The Uses of Benzyl methacrylate

Benzyl methacrylate is an important raw material and intermediate used in organic synthesis, pharmaceuticals and agrochemicals.

Flammability and Explosibility

Not classified

Advantages

The Tg of the copolymer was elevated, while thermal stability was first increased and then decreased with the introduction of Benzyl methacrylate. Besides, the water resistance of the latex PSA was improved by the presence of BzMA, which was confirmed by water contact angle measurements. Furthermore, as the BzMA content increased, the gel content slightly decreased, while sol molecular weight (Mw, Mn) of the polymer increased. Finally, with respect to the adhesive properties of the PSA, it was observed that loop tack decreased, while shear strength increased with the incorporation of BzMA. 180° peel strength initially increased and then decreased with the addition of Benzyl methacrylate from 0 to 30 wt%, with a maximum value at 5 wt%.
