DRAG REDUCING AGENT

This invention relates to drag reducing agents used in case of transportation of crude oil products, in particular, to solid dry poly(meth)acrylate with dry poly alpha-olefins powders based agents. The technical result of the solution involves the preparation of an effective, fast-dissolving, stable solid dry drag reducing agent suitable for use in heavy crude oil. The drag reducing agents compositions have better drag reducing performance in heavy crude applications as compared with traditional drag reducing slurries is also disclosed, which consists of the following components, wt%: a mixture of at least two drag reducing polymers, from 65 to 90 a separating agent from 3 to 25 anti-agglomerating agent from 3 to 25 a surfactant from 3 to 25,where the first polymer is poly(meth)acrylate, the second polymer is poly alpha-olefin, the ratio of the polyacrylate weight and polyalphaolefin weight varies in the range from 2:1 to 5:1.

Composition having excellent permeability to water vapour

A composition including a solution at least one acrylic adhesive and particles of a cross-linked polymer having a carboxylate-group density between 2.0 and 12.0 meq/g and an average pore size between 0.005 and 1.0 μm, usable in particular for creating an adhesive matrix suitable for any device, for example for medical aims such as a patch, a film, a strip or a dressing, preferably a dressing, or suitable for any device of the functional textile type such as a sports item.
