Abstract (en)

[origin: WO9850210A1] There is provided a preferred process for continuous mill mixing which comprises: (i) blending a gas-phase produced elastomer and one or more other compounding ingredients in a dry blender (distributive mixing), (ii) feeding the blend to an open roll mill for compounding into sheets or strips (dispersive mixing). A vulcanizing system can be introduced in either the dry blending (i) or mill mixing compounding (ii) step, but is preferably introduced during dry blending.
