  • Patent number: 7344673
    Abstract: A preform for a multi-layered hollow vessel has excellent moldability and productivity and is free from the deterioration of the characteristic properties of the vessel even when a recycled material is filled in large quantities. A molded product is produced by filling a first material and a second material into the cavity of an injection mold in a single molding step including (i) the substep of injecting the first material, (ii) the substep of injecting the first material and the second material at the same time and (iii) the substep of injecting the first material which are carried out continuously in this order.

  • Patent number: 6147016
    Abstract: A laminate sheet comprising (A) a polyester block copolymer which comprises 20 to 70 wt % of a hard segment consisting of an aromatic polyester and 80 to 30 wt % of a soft segment consisting of an aromatic polyester and (B) cloth on at least one side of which the polyester block copolymer is laminated, the melting point (T,.degree. C.) of the polyester block copolymer satisfying the following expressions: T0-5 >T>T0-60 and T>T'+10 (in which T is defined above, T0 is a melting point (0.degree. C.) of the aromatic polyester constituting the hard segment, and T' is a melting point (.degree. C.) of a random polymer obtained by adding 0.1 wt % of titanium tetrabutoxide to the polyester block copolymer and melting and kneading at 250.degree. C. for 3 hours).
