They give moldings, such as sheets and films, which combine a sufficient strength with tear resistance. When the copolymers are ones having a branched structure, they give a molding having excellent mechanical properties. The moldings obtained from compositions containing either of these copolymers are excellent in elongation and biodegradability and have a satisfactory balanc therebetween.

  • Patent number: 6316579
    Abstract: A thermoplastic resin composition can be obtained by adding about 0.1 to 20 parts by weight of a diene-series block copolymer (2) to 100 parts by weight of a resin composition containing a polycarbonate-series resin (1) as a basic component of which the proportion of terminal hydroxy groups relative to the whole of the terminals is 1 mole % or above (about 5 to 40 mole %). The polycarbonate-series resin base may further comprise a thermoplastic resin composition (3) such as a rubber-modified styrenic resin. The block copolymer component (2) includes an epoxy-modified block copolymer, etc. When added an organophosphorus compound as a flame retardant (4), or a fluorine-containing resin as a flame-retartant auxiliary (5), a halogen-free flame-retardant thermoplastic resin composition can be obtained. A thermoplastic resin with an improved flowability and impact strength can be obtained by modifying a polymer blend of the polycarbonate-series resin and the styrenic-series resin in quality.

  • Patent number: 5693722
    Abstract: A process is disclosed whereby a polymeric resin (containing ester and/or carbonate bonds) is readily converted into a resin having a modified molecular structure. Accordingly, a polycyclic carbonate (a monomer or oligomer) is transesterified with the polymer resin in the melt, preferably upon extrusion, optionally in the presence of a catalyst. Significantly, the cyclic carbonates are, by the inventive process, inserted into the structure of the polymer, effecting branching of the molecular structure, a branching which manifests itself in the modified properties of the resin.
