Method for producing a plastic bottle, and preform and blowing mold suited therefore are disclosed. An exemplary process can produce a plastic bottle, for example, a PET bottle. Such a bottle can be produced from a preform which has a body which is closed on one side, which is connected to a neck section with a pour opening, in which the preform which has been produced in a plastic injection process or an extrusion process is placed in the mold cavity of a blow mold and inflated using the blow nozzle by overpressure according to the mold cavity. Sealing can take place between the blow nozzle and the preform within the preform.

The present invention relates a mobile electronic device comprising at least one part made of a polymer composition comprising for more than 80% by weight (% wt.) relative to the total weight of the composition (C) of an aromatic polysulfone polymer comprising a residual chlorine content in an amount of less than 25 eq/g polymer.

A method for altering the appearance of molded articles is described herein. The method includes the steps of providing a plurality of articles; feeding a first article to a conveyor; transporting the first article to a treatment station; activating an activatable colorant of the first article by exposing the first article to at least one energy source, thereby causing a color change in the first article; manipulating the exposure of the first article to create a first discernable pattern in the first article; feeding a second article to the conveyor; transporting the second article to the treatment station; activating an activatable colorant of the second article by exposing the second article to the at least one energy source, thereby causing a color change in the second article; and manipulating the exposure of the second article to create a second discernable pattern in the second article.

A method for fabricating a preform (100) by providing a plurality of preform segments (101-103) which each define a portion of a preform (100), positioning said preform segments (101-103) in continuous contact with each other along at least one edge of said preform segments (101-103) such that said plurality of preform segments (101-103) define a cavity (107), and bonding each of said preform segments (101-103) to at least one other preform segment such that said plurality of preform segments (101-103) forms a continuous whole.

The present invention discloses a single layer rotomolded article prepared from a blend of polyethylene, functionalized polyolefin and one or more resins selected from polyetherester or saturated polyester or polycarbonate or polyamide.

The present application relates to a technical field of plastic article, and in particular, to a degradable plastic bottle, a preparation method therefor and a degradation method therefor. The bottle is prepared by blowing a combined degradable material formed by melting and extruding a resin mixture, the resin mixture includes the following components in parts by weight: 10-60 parts of polylactic acid, 20-50 parts of polybutylene adipate terephthalate, 0.5-20 parts of polymethyl ethylene carbonate, 0.5-20 parts of polyglycolic acid, and 1-10 parts of calcium carbonate.

Means for solving the problems The thermoplastic resin composition (X1) of the present invention comprises (A1), (B1), (C1), and optionally (D1) below: 1 to 90 wt % of an isotactic polypropylene (A1); 9 to 98 wt % of a propylene/ethylene/-olefin copolymer (B1) containing 45 to 89 mol % of propylene-derived structural units, 10 to 25 mol % of ethylene-derived structural units, and optionally, 0 to 30 mol % of C.sub.4-C.sub.20 -olefin-derived structural units (a1); 1 to 80 wt % of a styrene-based elastomer (C1); and 0 to 70 wt % of an ethylene/-olefin copolymer (D1) whose density is in the range of 0.850 to 0.910 g/cm.sup.3, wherein (A1)+(B1)+(C1)+(D1)=100 wt %.

A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.

Propylene copolymer having a melt flow rate MFR.sub.2 (230 C.) in the range of more than 0.5 to below 2.5 g/10 min, a xylene cold soluble content (XCS) in the range of 30.0 to 40.0 wt-%, a comonomer content in the range of more than 7.5 to 12.0 wt.-%, wherein further the comonomer content of xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of 16.0 to 28.0 wt.-%.
