[0095] Synthesis of α-methylstyrene-group-containing oligomers (AMSPU) >
[0096] 120.60 g of TMI and 600.00 g of JEFFAMINE (trademark) D2000 were mixed and reacted at room temperature for one day and one night without temperature adjustment. Confirmed by the results of IR spectrophotometry, the wavenumber is 2,265cm -1 The peak caused by the isocyanate disappears, and the reaction is concluded. In this way, α-methylstyrene-group-containing oligomers (AMSPU) are obtained.
[0097] Initiator >
[0098] Materials used for the initiators are shown in Table 1. Triethylborane:1,6-hexa 35% CX-100 solution of methylenediamine complex (TEB / HMDA / CX-100). Weigh 33.90g TEB / HMDA / CX-100, 62.30g AMSPU, 3.60g TS 720 and 0.20g M 460 in a 200-mL glass bottle, and use "Awatori rentarō" ARE-500 (Thinky (Thinky Corporation, Chiyoda-ku, Tokyo, Japan) with a planetary mixer) was stirred at 2,000 rpm for 2 minutes to obtain an initiator. The resulting initiators were used in Examples 1 to 5...
