Dihydrodicyclopentadiene copolymers and their uses

Dihydrodicyclopentadiene copolymers and their uses. (Mitsui Petrochemical Industries, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59164312 A2 17 Sep 1984 Showa, 20 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F032-06. ICA: C09J003-14. APPLICATION: JP 83-38274 10 Mar 1983. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 38, 39 Dihydrodicyclopentadienes ~ 2-80, dicyclopentadienes 0- ~90, and indenes ~ 10-90 mol% are polymd. to prep. resins for coatings, adhesive tackifiers, and rubber additives. Thus, 9,10-dihydrodicyclopentadiene (purity 79.1%) 340, indene 29, dicyclopentadiene 33, BF3.PhOH complex [372-44-1] 6.6,and PhMe 4.6 g were polymd. 2 h at 60° to prep. 83 g polymer [94228-75-8].

Sulfonates

Sulfonates. (Japan Synthetic Rubber Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59184152 A2 19 Oct 1984 Showa, 15 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C143-24. ICA: C04B013-28. APPLICATION: JP 83-57398 1 Apr 1983. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Section cross-reference(s): 58 Norbornene compds. contg. 2 double bonds and 9-12 C or C8-12 cyclohexene compds. contg. 2 double bonds react with benzenes to form adducts, which are sulfonated and condensed with HCHO to prep. dispersing agents for cement. Thus, a soln. contg. 1400 g 5-vinyl-1-norbornene and 320 g toluene was added to 1270 g toluene contg. 20 g BF3.Several reagents such as 372-44-1 is used here.PhOH complex [372-44-1] at 50° during ~1 h, kept for an addnl. 2 h to give 279 g adduct, mixed (100 g) with 50.0 g NaHSO3, 4.0 g KNO3, 700 mL MeOH, and 200 mL H2O, and stirred 5 h at 115° under N to prep. 76 g sulfonate (for subsequent condensation with HCHO). .
