  • Publication number: 20140194575
    Abstract: A crosslinkable bioplasticizer is disclosed, a mixture of an epoxy-functional bio-derived plasticizer and an aromatic dianhydride. When heated, the mixture crosslinks, which can be accelerated by the addition of a Lewis Acid metal catalyst. The crosslinked bioplasticizer can be melt compounded into a thermoplastic resin or can be formed in situ in the thermoplastic resin. The crosslinking of the bioplasticizer can reduce blooming of the bioplasticizer to the surface of a plastic article made by extrusion, molding, calendering, or thermoforming techniques.

  • Publication number: 20120070545
    Abstract: A method and system for oxygen molecule scavenging is disclosed. The system employs as an amphiphilic dendritic polymer as the reducing agent for oxygen molecules in a thermoplastic compound. Clarity of the compound, nearly the same as thermoplastic matrix itself in the compound, is achieved by the addition of an epoxy-functional styrene-acrylate oligomer. Food and beverage containers now made of polyethylene terephthalate can be molded from the compound and have substantially the same haze as the polyethylene terephthalate itself but with the oxygen scavenger to maintain freshness of the food or beverage from oxidation.

  • Publication number: 20110159937
    Abstract: A direction detection device is provided for a game machine combined exercise bike. The direction detection device include a detection module mounted to a direction rotation module composed of a rotatable portion and a fixed portion. The detection module includes a plurality of signal receiver elements and a signal transmitter element, which are operated in a non-contact manner and are allowed for relative rotation with respect to each other. Each signal receiver element has a range of detection. During relative rotation between the signal transmitter element and the signal receiver elements, when the signal transmitter element is moved into the detection range of one of the signal receiver elements, the signal receiver elements detect a positional message of the signal transmitter element, and the signal receiver elements applies the message to a signal processing device of the game machine, which converts the positional message into a direction signal.
