Injecting a first feed comprising ethylene and optionally a chain transfer agent system (CTA system) into a first autoclave reactor zone operating at polymerization conditions to produce a first zone reaction product, the CTA system of the first reactor zone having a transfer activity Z1; and B. (1) Transferring at least part of the first zone reaction product to a second reactor zone selected from a second autoclave reactor zone or a tubular reactor zone and operating at polymerization conditions, and, optionally, (2) freshly injecting a second feed into the second reactor zone to produce a second zone reaction product, with the proviso that the second reactor zone contains a CTA system having a transfer activity Z2; and with the proviso that the ratio of Z1/Z2 is less than 1.Type: GrantFiled: April 28, 2014Date of Patent: August 2, 2016Assignee: Dow Global Technologies LLCInventors: Otto J.

Publication number: 20080000207Abstract: A crop-processing device with a picking-up and cutting device for picking up and cutting an agricultural product. The crop-processing device furthermore has a discharge duct for discharging cut agricultural product from the crop-processing device, in which discharge duct first and second rotating accelerating elements are arranged for conveying the cut agricultural product through the discharge duct by contact with the cut agricultural product. The peripheral speed of the second accelerating element is greater than the peripheral speed of the first accelerating element. As a result, the acceleration up to the desired discharge speed, and thus the discharge of the product, is more uniform. Furthermore, the device requires less power than known crop-processing devices.Type: ApplicationFiled: June 20, 2007Publication date: January 3, 2008Inventors: Sjoerd De Vries, Cornelis Christianus Havermans

Patent number: 5795941Abstract: Crosslinkable polyolefin compositions, articles prepared from such compositions, and processes for making such compositions are described that possess both good processability and fast cure rates. The crosslinkable polyolefin compositions are bidisperse blends of ethylene polymers of the same polymer family having differing number average molecular weights as obtained by deconvolution in which M.sub.n1 /M.sub.n2 >7, M.sub.n2 >3000 and 0.7.gtoreq.(A.sub.1 /(A.sub.1 +A.sub.2)).gtoreq.0.15 wherein M.sub.n1 represents the number average molecular weight of the first deconvoluted component, M.sub.n2 represents the number average molecular weight of the second deconvoluted component, and A.sub.1 and A.sub.2 are the relative proportions of the first and second components.Type: GrantFiled: October 3, 1995Date of Patent: August 18, 1998Assignee: The Dow Chemical CompanyInventors: Stephen H.
