Method for sterilization of polyvinyl alcohol gel by .gamma.-ray

A container for storing blood for a long period of time to keep the quality of the blood in good condition, is formed of a laminated film type bag composed of at least one thermoplastic resin film layer and at least one addition polymerization type silicone rubber film layer, the surface of the laminated film which comes in direct contact with the blood is made of the addition polymerization type silicone rubber film layer; the thermoplastic resin film layer has a permeability to carbon dioxide gas of 6,000 to 70,000 ml/m.sup.2.24 hr. for a thickness of 0.025 mm at 25.degree. C.; and the whole laminated film type bag has a permeability to carbon dioxide of 5,000 ml/m.sup.2.24 hr.atm at 25.degree. C. for storing whole blood and packaged red blood cells, and a permeability to carbon dioxide of 2,000 to 9,000 ml/m.sup.2.24 hr. atm at 25.degree. C. for storing platelet preparations.

A thermoplastic resin-silicone composite shaped article comprising (a) a shaped article of a thermoplastic resin selected from the group consisting of olefin resins, urethane resins and styrene resins and (b) a cured layer of an additional polymerization type silicone composition adhering to the one or both surfaces of the shaped article of a thermoplastic resin. To the surface of the above shaped article of a thermoplastic resin to which the above cured layer of an additionl polymerization type silicone composition does not adhere, there may adhere another cured layer of the above addition polymerization type silicone composition. To either or both of these cured layers, there may further adhere a layer of the above thermoplastic resin, other thermoplastic resin, a silicone rubber, a silicone resin, glass, ceramics or a metal.

A thermoplastic resin-silicone rubber composite shaped article comprising (a) a shaped article of a thermoplastic resin selected from the group consisting of soft vinyl chloride resins, olefin resins, urethane resins and styrene resins and (b) a cured layer of an addition polymerization type silicone rubber composition adhering to the one or both surfaces of the shaped article of a thermoplastic resin. To the surface of the above shaped article of a thermoplastic resin to which the above cured layer of an addition polymerization type silicone rubber composition does not adhere, there may adhere another cured layer of the above addition polymerization type silicone rubber composition. To either or both of these cured layers, there may further adhere a layer of the above thermoplastic resin, other thermoplastic resin, a silicone rubber, a silicone resin, glass, ceramics or a metal.

Thermoplastic resin-silicone rubber composite shaped article

A soft vinyl chloride resin-silicone composite shaped article consisting of a soft vinyl chloride resin shaped article and a cured layer of an addition polymerization type silicone composition adhered to the surface of the vinyl chloride resin shaped article, wherein said addition polymerization type silicone composition contains an organohydrogenpolysiloxane having at least two hydrogen atoms directly bonding with silicon atoms in each molecule, in an amount enough to provide one to six such hydrogen atoms per one vinyl group of the silicone composition. The above composite shaped article has a very high bonding strength between the vinyl chloride resin shaped article and the cured layer of an addition polymerization type silicone composition.
