Abstract: A method for recycling polyethylene terephthalate, including obtaining flakes of polyethylene terephthalate which are re-polymerized using heat and/or a chain extender combined with an anti-yellowing agent to yield an average molecular weight of at least 40,000 Da and a tunable intrinsic viscosity of approximately 0.5 dl/g to 0.8 dl/g. Polyethylene terephthalate pellets are produced having a color deviation of approximately 2.5 or less from the re-polymerized 100 percent post-consumer polyethylene terephthalate flakes as raw material for formation of polyethylene terephthalate products. When compared to available rPET bottles, CIELAB color values show indiscernible color differences with the high quality rPET produced. Consequently, the high-quality rPET pellets produced are capable manufacturing PET bottles with 100% PCR content and a high number of repeated recycling cycles.

Abstract: A communication method is applied to a communication system using a forward error correction (FEC) technology. In the communication method, a header field of a first data transmission unit sent by a transmit end apparatus may indicate a modulation manner of a second data transmission unit after the first data transmission unit, so that a receive end apparatus can determine, based on the header field of the received first data transmission unit, the modulation manner of the second data transmission unit after the first data transmission unit. Then, before FEC decoding is performed on the second data transmission unit, the receive end apparatus may complete demodulation of the second data transmission unit based on the determined modulation manner such that FEC decoding can be performed on a header field and a load field of the second data transmission.
