Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a cycloolefin polymer composition. More specifically, it relates to a cycloolefin polymer composition containing a cycloolefin polymer and having excellent impact resistance.

[0002]

BACKGROUND OF THE INVENTION The present applicant has previously found that a cyclic olefin-based random copolymer obtained by copolymerizing ethylene with a cyclic olefin such as tetracyclododecene or norbornene has excellent transparency and heat resistance. Is a synthetic resin that has a good balance of properties, heat aging resistance, chemical resistance, solvent resistance, dielectric properties, and rigidity, and also demonstrates excellent performance in the field of optical materials such as optical memory disks and optical fibers. The heading has already been disclosed in JP-A-60-168708, JP-A-61-98780, and JP-A-61-11.
5912, JP 61-115916, JP 61-120816, JP 62-2524.
No. 07 publication. The cyclic olefin random copolymers described in these publications are also known to exhibit excellent performance in the field of structural materials.

However, although these cyclic olefin-based copolymers have excellent heat resistance and rigidity, there is room for improvement in impact resistance, and the transparency possessed by these cyclic olefin-based copolymers is maintained. At the same time, further improvement in impact resistance is required.

Further, the applicant of the present invention has found that a specific softening temperature (TM
A composition comprising a cyclic olefin-based random copolymer having A) and a specific α-olefin-based elastic copolymer,
It has been found that a resin having improved impact resistance can be obtained without impairing excellent properties such as heat resistance, heat aging resistance, and chemical resistance, and it has already been proposed in JP-A-1-163241.

Further, the present applicant has proposed, as a cycloolefin polymer composition having improved impact resistance, a specific cyclic olefin random copolymer and a specific soft copolymer as an organic peroxide. A cyclic olefin-based copolymer composition comprising a product obtained by the reaction in the presence of the above has been already proposed in JP-A-2-167318.

However, the cycloolefin polymer compositions proposed in JP-A-1-163241 and JP-A-2-167318 have improved impact resistance, but are not sufficiently transparent. No, there was room for improvement.

When radically reacting each component, it is desirable to react at a temperature at which the organic peroxide decomposes.
In the reaction, each raw material can be mixed and reacted at the same time, but a method of mixing both and then reacting by mixing an organic peroxide and, if necessary, a radically polymerizable polyfunctional monomer is preferable. . The organic peroxide is preferably added in a state where the respective components are sufficiently mixed.

To mix the components, the separately prepared components are melt-blended with an extruder or the like, or the components are mixed with an appropriate solvent (eg, heptane, hexane, decane,
Saturated hydrocarbons such as cyclohexane; aromatic hydrocarbons such as toluene, benzene, xylene, etc.) can be sufficiently dissolved or dispersed and blended.

An organic peroxide and, if necessary, a radically polymerizable polyfunctional monomer are added to the mixture of the components thus obtained and blended, and the mixture is reacted at a temperature at which the organic peroxide decomposes.

Such a radical reaction can be carried out in a molten state of the mixture of raw materials, or in a solution state in which the mixture of raw materials is dissolved or dispersed in a solvent. When the radical reaction is carried out in the molten state, a kneading device such as a mixing roll, a Banbury mixer, an extruder, a kneader, a continuous mixer or the like is used to melt and mix the mixture of raw materials to react. The radical reaction is carried out at a temperature equal to or higher than the one-minute half-life of the organic peroxide, usually 150 to 300.
C., preferably 170 to 270.degree. C., usually 10 seconds to 30 minutes, preferably 3 to 10 minutes.

As the solvent used when the radical reaction is carried out in the state of being dissolved or dispersed in the solvent, the same solvent as the solvent used in the solution blending method can be used. The radical reaction is preferably carried out at a temperature not lower than the 10-minute half-life of the organic peroxide, usually at a temperature of 50 to 300 ° C., usually for 10 seconds to 2 hours.
