摘要:
A resin composition comprising 100 parts by weight of an aggregated inorganic layer compound and 200-10,000 parts by weight of a resin, the particle size of the aggregated inorganic layer compound satisfying the mathematical expressions (1): 5 wherein L is the average particle diameter of the inorganic layer compound before aggregation and D is the average particle diameter of the inorganic layer compound after aggregation (average aggregated particle diameter), and a process for producing the resin composition described above which comprises a process of dispersing the inorganic layer compound in a dispersion medium to obtain a liquid dispersion of the inorganic layer compound, a process of aggregating the inorganic layer compound present in the liquid dispersion obtained by process 1, and a process of compounding the liquid dispersion of the inorganic layer compound aggregated by process 2 with the resin. The resin composition of the present invention is excellent in gas barrier property, particularly in oxygen barrier property.
摘要:
A resin composition comprising 2 to 30 wt. parts of polyaminoamide and 98 to 70 wt. parts of a saponified ethylene-vinyl ester copolymer which comprises 20 to 60 % of ethylene units based on the whole monomeric units and has a saponification degree for the vinyl ester units of at least 90 %, and a shaped article comprising this resin composition.
摘要:
A polyolefin resin covering film having a first layer of a polyolefin resin and second and third layers which are provided on respective sides of the first layer and made of a polyolefin resin containing 20 wt. % or less of a polar group-containing vinyl monomer, in which the polyolefin resin covering film contains 6 to 50 wt. % of a IR absorber based on the weight of the covering film, and has a IR absorbance of 70 to 85 % at 27°C, which covering film is preferably used as a covering film of a green house or tunnel for protected horticulture to raise a strong-light produce.
摘要:
A gas barrier resin composition or its film having very high level gas barrier and moisture barrier properties, which comprises a resin and an inorganic laminar compound having a particle size of 5 µm and an aspect ratio of 50-5,000. Said resin composition or its film can be produced by dispersing an inorganic laminar compound in a resin or resin solution in the state that the inorganic laminar compound is swollen or cloven with a solvent, and removing the solvent from the dispersion, if necessary in the form of a film, while keeping said state.
