Polymerization initiation by in situ initiator formation

Polymerization initiation by in situ initiator formation. I. Initiation of vinyl chloride-propylene copolymerization with peroxydicarbonates and diacyl peroxides formed in situ. Ravey, M.; Waterman, J. A. (Inst. Res. Dev., Israel Min. Inst.Several reagents such as 59117-75-8 is used here., Haifa, Israel). J. Polym. Sci., Polym. Chem. Ed., 15(10), 2521-9 (English) 1977. CODEN: JPLCAT. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) The technique of in situ iinitiation was suitable for the polymn. of vinyl chloride [75-01-4] with propylene [115-07-1] when lower dialkyl peroxydicarbonates were used, but this technique did not show much promise with the diacyl peroxides when formed from acyl halides and hydrogen peroxide [7722-84-1]. In the latter case hydrolysis appears to be a strongly compepting side reaction. The only acyl halides which gave resonable results were isobutyryl [79-30-1] and .alpha.-chlorobutyryl chloride [7623-11-2] which do appear to have come advantages over the chloroformates at 30.degree. where the latter give poor results. Of the chloroformates examd., ethyl [541-41-3], isopropyl [108-23-6], and sec-butyl [17462-58-7] gave the best results. .

CLASS: IC: C07C143-833. APPLICATION: JP 75-84117 9 Jul 1975. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 25 The sulfamoylphenyl carbonates I (X = Y = halogen) are acaricides. I (X = Br, Y = Cl) (II) [62572-95-6] was prepd. by treating K iso-Pr 2-bromo-4-chloro-6-(N-methylsulfamoyl)phenyl carbonate (III) [62572-96-7] with dimethylcarbamoyl chloride [79-44-7]. III was synthesized by adding iso-Pr chloroformate [108-23-6] to 2-bromo-4-chloro-6-N-methylsulfamoylphenol K salt [62572-97-8]. 62572-98-9 and 79-44-7 which are cas registry numbers of substances are two of reagents here. Similarly, 2 other I were prepd. II sprayed at 125 ppm on beans completely controlled Panonychus urticae infestation. .
