Compatibility and viscoelastic properties of n-butyl acrylate-ethylene copolymer hot melts containing tackifiers of different nature

摘要

Brookfield viscosity of EBA hot melts did not vary significantly by changing the tackifier nature but pseudoplasticity was observed. The higher compatibility was obtained with pentaerythritol rosin ester, leading to higher elastic modulus and hot tack, and maximal T-peel and single lap-shear adhesion.
