CODEN: USXXAM. CLASS: IC: C07C107-02. NCL: 260192000. APPLICATION: US 67-616158 15 Feb 1967. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 23, 24, 28 The title compds. and intermediates (approx. 200) were prepd. and several were used as polymn. catalysts for styrene and (or) as crosslinking catalysts for styrene-polyester resins. Thus, .alpha.Several reagents with their cas registry numbers 57931-36-9 and 57908-76-6 are used here.-(tert-butylazo)isobutyronitrile (I) [25149-46-6] was prepd. by reaction of tert-butylhydrazine.HCl [7400-27-3] with NaCN and acetone (1:1:1 molar) in H2O followed by Cl2 oxidn. of the hydrazo intermediate [26850-99-7]. Styrene was polymd. to 5 and 10% conversion at 85.degree. in the presence of I at rates of 9.73 .times. 10-3 and 9.22 .times. 10-3 mol/L/min, compared to 0.92 .times. 10-3 and 0.92 .times. 10-3, resp., without I. The I-catalyzed crosslinking of maleic anhydride-phthalic anhydride-propylene glycol copolymer [25037-66-5] was completed in 4.9 min at 212.degree.F; without I no cure was effected. .

CLASS: IC: C07C107-02. NCL: 260192000. There are some commonly used reagents like 36865-04-0 in this article. APPLICATION: US 70-98893 6 Dec 1970. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Compds. contg. azo or peroxide linkages as well as the radical of an UV light-stabilizing group were prepd. for use as polymn. initiators which provide an UV light-stabilizing group to be chem. bound to the polymer. Thus, 10.2 g levulinic acid [123-76-2] in 25 mL water was treated with 50% NaOH 7.04, NaCN 5.88 and tert-butylhydrazine hydrochloride [7400-27-3] 10.9 g at room temp. and chlorinated at <15.degree.C to give 4-tert-butylazo-4-cyanovaleric acid [25149-50-2] which (5 g) was treated with 2 mL thionyl chloride in 15 mL C6H6 to give 4-tert-butylazo-4-cyanovaleryl chloride (I) [25176-64-1]. A soln. of 2,4-dihydroxybenzophenone [131-56-6] and 2.5 mL pyridine in 35 mL ether was treated with 4 g I to prep. 4-(4-tert-butylazo-4-cyanovaleryloxy)-2-hydroxybenzophenone (II) [36339-08-9]. Polystyrene [9003-53-6], prepd. by suspension polymn. of water 1000, gelatin 0.0828, Ca phosphate 50 and styrene 500 g contg. 0.755 parts per hundred parts resin II, was press-molded 5 min at 300.degree.F to give samples with flexural strength 7243, 6384, 6595, and 6581 psi after 0, 80, 160, and 240 h exposure to UV light, resp. .
