Example Embodiment
[0483] Example
[0484] Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited by the following examples. However, unless otherwise specified, "%" and "part" are quality standards.
[0485]
[0486] As shown below, chain transfer agents B-1 to B-12 (the aforementioned thiol compounds represented by the general formula (3)) were synthesized.
Example Embodiment
[0487] [Synthesis Example B-1]
[0488] In 93.60 parts of dimethylformamide were dissolved 7.83 parts of dipentaerythritol hexa(3-mercaptopropionate) [DPMP; manufactured by Sakai Chemical Industry Co., Ltd., the following compound (33)] and 15.57 parts of which have adsorption sites and carbon -The compound of carbon double bond (the following compound (A-1)) was heated to 70 degreeC under nitrogen flow. Thereto was added 0.06 part of 2,2'-azobis(2,4-dimethylvaleronitrile) [V-65, manufactured by Wako Pure Chemical Industries, Ltd.], followed by heating for 3 hours. Furthermore, 0.06 part of V-65 was added, and it was made to react at 70 degreeC under nitrogen flow for 3 hours. By cooling to room temperature, a 20% solution of the thiol compound (chain transfer agent B-1) in the present invention shown below was obtained.
[0489]
Example Embodiment
[0490] [Synthesis Example B-2]
[0491] 15.57 parts of compound (A-1) having an adsorption site and carbon-carbon double bond and 93.60 parts of dimethylformamide in the above synthesis example B-1 were changed to 14.61 parts having an adsorption site and carbon-carbon double bond The thiol compound (chain transfer agent B- 2) 20% solution.
