Abstract: Acrylates and methacrylates were obtained by oxidative esterufucation of propylene or isobutylene (I) in the presence of O and C2H4 or an alc., in a single fluidized bed reactor contg. oxidn. catalysts at 200-600≦̸C. A reactor was charged with 80% 50:50 mixt. of Ni2.5Co4.5Fe3BiPO.5/0.5Mo12Ox and SiO2 and 20% 62:38 mixt. of V3W1.2Mo12Ox and SiO2.Air-I-MeOH(10:1:2) was fed to the reactor at 355oC and 1 atm. and after contact time 5 s the product yield was methyl methacrylate 30.0, I 53.0, acrolein 1.0, and methacrolein 2.0 mol. percent with a trace of methacrylic acid.

Abstract: A process for continuously polymerizing from the vapor state at least one polymerizable monomer or a mixture can be economically and efficiently converted to polymeric substance with a high yield catalyst in a vapor phase polymerization process using a stirred-bed, quench cooled, horizontal reactor together with essentially off-gas recycle and melt finishing. The method is further characterized by being essentially isobaric at least up to the polymer finishing steps.

Abstract: Acid-activated mercaptans are used as chain transfer agents in the copolymn. of acrylonitrile(I), giving high conversions to polymers with high nitrile content and good processability. Thus, 75 parts I and 25 parts Me acrylate were added to compn. contg. Na dioctyl sulfosuccinate 0.85, poly (vinylpyrrolidone) 0.30, water 205, nitrile rubber(added as latex) 9, and H3PO4 0.067 parts. The polymn. mixt. was heated to 54≦̸C, treated with 0.06 parts K2S2O8 and 1.2 parts pentaerythritol tetrakis(3-mercaptopropionate) and polymd. 3.5h, giving a polymer with av. mol. wt. 126,885 and Brabender torgue at 230≦̸ and 35 rpm 2/20m-g after 10 min
