A method for producing a (poly)alkylene glycol monoalkyl ether includes reacting an olefin and a (poly)alkylene glycol in a reactor in a presence of a catalyst. The method also includes recovering at least a portion of raw materials used for the production to use the recovered raw materials again as a raw material, where at least one of the recovered raw materials contains an olefin. A mass of a branched olefin relative to a mass sum of the branched olefin and a linear olefin contained in the recovered raw materials is controlled not to exceed 20 mass %.

A multilayer film includes a first layer (A), a third layer (C), and a second layer (B) sandwiched between the first layer (A) and the third layer. Each layer (A, B, C) includes at least one propylene polymer selected from propylene homopolymers, multiphase polymers, propylene copolymers having at least one comonomer selected from ethylene and linear or branched C4-C12 α-olefins, and mixtures thereof. In the second layer (B), the propylene polymer has a melt flow rate (MFR) of not more than 5 g / 10 min, wherein the melt flow rate is determined according to ISO 1133.
