Abstract: Injection moldable thermoplastic polyolefin resins containing from about 20 to about 40 wt % EPR dispersed in a continuous highly isotactic polypropylene having good paintability. Reactor prepared resins, or RTPO resins, containing highly isotactic polypropylene and from 20 to 30 wt % of an EPR component comprising from about 40 to about 55 wt % ethylene are particularly attractive for use in the production of automotive trim and fascia.

Abstract: Binary indications are converted to an analog representation with significant reduction in ringing at the transitions between successive binary indications and in the period during each binary indication. The binary indications are disposed in a row-and-column matrix to provide a thermometer code. Each stage of the converter includes a decoder and latch arranged so the decoder inputs settle before the latch is set by the clock pulses. The stages are implemented in complementary CMOS. Complementary transistors are biased so one transistor of the pair is driven to the rail while the other transistor of the pair floats. A dummy CMOS transistor is used to balance the number of transistors in the decoder paths.

Abstract: In a gas phase olefin polymerization using a transition metal compound/aluminum alkyl catalyst system, polymerization can be terminated rapidly by injecting an amount of carbon oxide and then restarting efficiently by addition of an amount of aluminum alkyl.
