The present invention relates to a continuous high-pressure polymerization process for the preparation of a liquid ethylene copolymer which comprises in polymerized form 20 to 60 wt % of ethylene; and at least 20 wt % of an acrylate, which is selected from C-Calkyl (meth)acrylate, where a monomer feed comprising the ethylene and the acrylate is polymerized in the presence of at least 2 wt % of a chain transfer agent. The invention further relates to the liquid ethylene copolymer obtainable by the polymerization process; and to a lubricant comprising the liquid ethylene copolymer obtainable by the polymerization process; and to a method for reducing friction between moving surfaces comprising the step of contacting the surfaces with the lubricant or with the ethylene copolymer.

High-pressure polymerization process for liquid ethylene copolymers

The present invention relates to a lubricant comprising a liquid ethylene copolymer which comprises in polymerized form 20 to 60 wt % of ethylene; and at least 20 wt % of an acrylate, which is selected from C1-C22 alkyl (meth)acrylate. It further relates to the liquid ethylene copolymer; and to a method for reducing friction between moving surfaces comprising the step of contacting the surfaces with the lubricant or with the ethylene copolymer.

According to the present disclosure, starch/polymer combinations are provided. The preferred starch/polymer combinations are usable as paper additives, in the wet end of a papermaking process. Typical and preferred starch/polymer combinations of this type, result from combining a starch, having a polymer reactive carbonyl functionality, with a polymer, having a carbonyl reactive functionality, under conditions that allow for covalent interaction between the two. Typically usable components comprise oxidized starch and polymer having reactive primary or reactive secondary amine groups. Also provided are methods of preparing such combinations, methods of use, preferred papers including such combinations, and, analytical techniques usable in preparation of such combinations.

Compositions suitable as additives in the paper industry, preparation; use; and, paper comprising such
