Problems solved by technology

[0011] However, even in the case of producing a molded body by any of the production methods, there is a problem that clogging is likely to occur in a hopper or the like in the step of producing pellets of the composition used as a raw material, or when pellets are charged into a production device, reduce productivity

Synthetic example 1

[0114]Put 800 parts of degassed and dehydrated cyclohexane, 20 parts of 1,3-butadiene and 0.03 parts of tetrahydrofuran into a reaction vessel replaced by nitrogen, and add n-butyllithium at the polymerization initiation temperature of 70°C 0.09 parts, for temperature-rising polymerization. After the polymerization conversion rate reached 99% or more, the reaction solution was cooled to 25° C. to prepare a polymer before hydrogenation. Then, 80 parts of 1,3-butadiene and 5 parts of tetrahydrofuran were added, and temperature-rising polymerization was further performed. After the polymerization conversion rate reached 99% or more, 0.06 part of dichloromethylsilane was added, and the temperature-rising polymerization was further performed. Then, 0.04 parts of diethylaluminum chloride and 0.06 parts of bis(cyclopentadienyl)furfuryloxytitanium chloride were put into the reaction container and stirred. The hydrogenation reaction was started at a hydrogen supply pressure of 0.7 MP...

Synthetic example 2

[0116] Put 800 parts of degassed and dehydrated cyclohexane, 20 parts of 1,3-butadiene and 0.03 parts of tetrahydrofuran into a reaction vessel replaced by nitrogen, and add n-butyllithium at the polymerization initiation temperature of 70°C 0.09 parts, for temperature-rising polymerization. After the polymerization conversion rate reached 99% or more, the reaction liquid was cooled to 45° C., 80 parts of 1,3-butadiene and 1 part of tetrahydrofuran were added, and then temperature-rising polymerization was carried out. After the polymerization conversion rate reached 99% or more, 0.06 part of dichloromethylsilane was added, and the temperature-rising polymerization was further performed. Then, 0.04 parts of diethylaluminum chloride and 0.06 parts of bis(cyclopentadienyl)furfuryloxytitanium chloride were put into the reaction container and stirred. Then, a hydrogenation reaction was performed in the same manner as in Synthesis Example 1 to obtain thermoplastic resin A-2.

Synthetic example 3

[0118] The thermoplastic resin A-3 was obtained by the method similar to the synthesis example 1 except having made hydrogenation reaction time into 2 hours.

[0119] 3.1.4. Synthesis Example 4, Synthesis Example 5, Synthesis Example 6

[0120] Except having changed the hydrogenation reaction time to 2 hours, 1 hour, and 40 minutes, respectively, thermoplastic resin A-4, thermoplastic resin A-5, and thermoplastic resin A-6 were obtained by the method similar to synthesis example 2.

Abstract

The present invention provides a product capable of improving productivity by suppressing clogging in the pellet drying step or hopper, etc., and having excellent molded product characteristics (low hardness, good visibility, heat resistance, good molded appearance, etc.) A composition and a molded body excellent in moldability of the molded body. The composition of the present invention contains a thermoplastic resin (A) having an iodine value of 2 to 150, and water, the composition contains 100 ppm to 2000 ppm of the water relative to 100 parts by mass of the composition, and the thermoplastic resin ( A) has a repeating unit derived from a conjugated diene compound, and the thermoplastic resin (A) has a crystal melting peak temperature of 50° C. to 95° C. and a crystal melting heat of 10 J / g to 40 J / g.

Description

technical field [0001] The present invention relates to a composition and a molded body produced using the composition. Background technique [0002] Conventionally, surface protection films have been used to protect the lens surfaces of prism sheets used in liquid crystal displays. The surface protection film is used to protect the lens surface of the prism sheet from damage or contamination during the manufacturing process, so it will be peeled off after the manufacturing process ends and will not remain in the final product. Therefore, the surface protection film requires (1) low hardness; sufficient contact area with the adherend; (2) good visibility; easy to perform work steps or appearance inspection; (3) heat resistance; shape at high temperature It is also stable, does not generate foreign matter, (4) has good molding appearance, and other molding characteristics. [0003] As such a surface protection film, for example, a film containing, for example, ethylene-viny...
