摘要： An improved gas-phase copolymerization process for producing copolymers of propylene and ethylene in multiple reactors using high activity Ti/Al catalysts is provided. The improvement consists of developing a control parameter derived from eight integral regions of the copolymer .sup.13 C NMR spectrum, defining the limits of the control parameter for the process, and operating the process to maintain the parameter within the defined limits. This is accomplished by adjusting the amount of ethylene in the primary and/or secondary reactor and adjusting other process variables as required.

摘要： A stationary plate assembly for a rheometer that selectively provides steady state and dynamic testing of melt viscoelastic characteristics of a material sample. The stationary plate assembly has a stationary sample plate magnetically coupled to its supporting member. Therefore, after the steady state testing is complete, the movable plate, material sample and stationary plate may be moved vertically away from the stationary plate supporting member. Therefore, any spurious, erratic rotations of the movable plate when the rheometer is switched form the steady state test mode to the dynamic test mode will not cause a further working of the material sample.

The copolymerization occurs at a temperature in the range of between in excess of ambient temperature and less than 100.degree. C. and at a pressure in excess of about 2,000 psi. The aliphatic polyester product of this process contains repeating structural units of the formula ##STR3## where A is a radical of a polymerized olefinic monomer; R is a bivalent moiety; x is a positive integer; and y and z are 0 or a positive integer with the proviso that the sum of y and z is at least 1, ratio of x to y is in the range of between about 3:1 and about 200,000:1, the ratio of z to y is in the range of between 0 and about 0.5:1; and said polyester has a weight average molecular weight of at least about 40,000.

摘要： A novel catalyst support and a method for preparation thereof, characterized by the presence of selected amounts of a hydrocarbon soluble magnesium-containing compound applied to the support relative to solvent, wherein a surface uniformly and essentially continuously moistened with the solvated magnesium compound is achieved in a condition of incipient precipitation to permit the formation of a regular essentially continuous distribution of the magnesium compound onto and conforming to the support material The drying process under these conditions is effective in maintaining to a high degree the effective surface area and pore volume of the material. The support containing the adsorbed magnesium is then dried in a controlled manner to essential incipient wetness conditions providing a regular spatial distribution of stacked reticular magnesium values at a level of one to five molecular monolayers on the support.A representative process for polymerizing or copolymerizing olefins providing stereospecific polymers such as propylene is disclosed.
