    Abstract: A high pressure polymerization process to form an ethylene-based polymer comprises the steps of: A. Injecting a first feed comprising a chain transfer agent system (CTA system) and ethylene into a first autoclave reactor zone operating at polymerization conditions to produce a first zone reaction product, the CTA system of the first reactor zone having a transfer activity Z1; and B. (1) Transferring at least part of the first zone reaction product to a second reactor zone selected from a second autoclave reactor zone or a tubular reactor zone and operating at polymerization conditions, and, optionally, (2) freshly injecting, a second feed into the second reactor zone to produce a second zone reaction product, with the proviso that at least one of the first reactor zone product and the freshly injected feed comprises a CTA system with a transfer activity of Z2; and with the proviso that the ratio of Z1:Z2 is greater than 1.

    Abstract: The invention is a formulation for use in the manufacture of carpets. The formulation is combined with polymers such as, but not limited to, ethylene vinyl acetate (EVA, a co-polymer) to provide carpet backing formulations which exhibit excellent tensile strength. The formulation of the invention can be provided to carpet manufacturers as a separate product to be added later to a polymer for a use in carpet backings. Alternatively, the formulation can be added to a polymer such as EVA or compositions comprising EVA and then applied to a carpet backing to provide a carpet with a carpet backing exhibiting excellent tensile strength.
