  • Article formed from propylene diene copolymers
    Publication number: 20010016639
    Abstract: The co-polymerization reaction of one or more olefin monomers, such as propylene, with &agr;,&ohgr;-diene units and the resulting copolymers are provided. More specifically, the copolymer may have from 90 to 99.999 weight percent of olefins and from 0.001 to 2.000 weight percent of &agr;,&ohgr;-dienes. The copolymer may have a weight average molecular weight in the range from 50,000 to 2,000,000, a crystallization temperature in the range from 115° C. to 135° C. and a melt flow rate in the range from 0.1 dg/min to 100 dg/min. These copolymers may be employed in a wide variety of applications, the articles of which include, for example, films, fibers, such as spunbonded and meltblown fibers, fabrics, such as nonwoven fabrics, and molded articles. The copolymer may further include at least two crystalline populations.
    Type: Application
    Filed: December 11, 2000
    Publication date: August 23, 2001
    Inventors: Pawan Kumar Agarwal, Weiqing Weng, Aspy Keki Mehta, Armenag Hagop Dekmezian, Christopher Ross Davey, Charlie Y. Lin, Michael Chia-Chao Chen, Galen Charles Richeson
