An objective of this disclosure is to provide a method of reusing a resin shaped product including an alicyclic structure-containing polymer, which can obtain a recycled article of the resin shaped product having reduced appearance defects and improved physical properties such as color tone. The presently disclosed method of reusing a resin shaped product including an alicyclic structure-containing polymer includes grinding the resin shaped product to obtain shaped product ground products; and dissolving the shaped product ground products in a mixed solvent containing not less than 80 weight % and not more than 98 weight % of cyclohexane and not less than 2 weight % and not more than 20 weight % of a hydrocarbon-based or aromatic solvent having a coagulation point of 40 C. or lower per 100 weight % of the mixed solvent to obtain a polymer solution.

A method for processing polyolefins may include contacting solid polyolefins with a solid catalyst to form a reaction mixture. The solid catalyst may be chosen from a zeolite, a microporous aluminosilicate, an alumina, or combinations thereof. The solid polyolefins may be chosen from polyethylene, polypropylene, or combinations thereof. The method may include mechanically agitating the reaction mixture to produce olefin-containing hydrocarbon polymers and separating the olefin-containing hydrocarbon polymers from the solid catalyst. The olefin-containing hydrocarbon polymers include a carbon-carbon double bond in the backbone of the hydrocarbon polymers.

A full recovery, recycling and regenerative method includes the polyester fibers being interwoven with elastic polyurethane fibers or elastic polyolefin fibers, or blended with regenerated cellulose fibers such as cotton, linen and viscose, by using titanium easily decomposed and recycled polyesters, and the complete separation of the fibers or blended fibers of the polyester fibers and the elastic fibers being achieved using the differences in chemical resistance and temperature resistance of various components. The polyester can be decomposed into small molecules under mild conditions of hydrolysis, alcoholysis and alkali hydrolysis. Under such mild conditions, the elastic polyurethane or elastic polyolefin fibers, or fibers such as the cotton, the linen, the viscose and nylon, are resistant to hydrolysis or alcohol, and will not decompose. The separation of the polyester fibers from other components is achieved. The other separated components are single loose components which can be recycled.

The invention relates to a method for manufacturing a pellet in a pellet mill, which method comprises the steps of (A) pressing a mixture for compaction by a roller through a nozzle to obtain a strand, and (B) comminuting the strand to obtain the pellet, wherein the mixture for compaction comprises (i) 87 to 97 wt. % of a polymer stabilizer, which is tris(2,4-ditert-butylphenyl) phosphite (CAS-No. 31570-04-4), and (ii) 3 to 13 wt. % of a processing aid, which is a propylene-ethylene copolymer and which possesses a melting enthalpy below 100 J/g at 101.32 kPa. The pellet is useful for a dust-free handling of its polymer stabilizer at a manufacturing of the stabilized polymer. Furthermore, a method for stabilizing a polymer, which is a polyolefin, a polystyrene or a mixture thereof, is disclosed, which comprises the dosing of the pellet to the polymer.
