  • Process for preparing halogenated polymer having reduced residual acidity and yellowness index of 3.5 and below
    Patent number: 10047177
    Abstract: The present disclosure provides a process for the reduction of residual acidity of halogenated polymer. The process involves treating the halogenated polymer to a physical process such as rotary vacuum drying and then neutralizing the treated halogenated polymer with alkaline metal salt solutions. The process requires less quantity of an economic neutralizing agent/base during chemical treatment, thus improving process economy without prejudicing quality of the final halogenated polymer.
    Type: Grant

  • Heterogeneous ziegler-natta catalyst system and a process for olefin polymerization using the same
    Patent number: 9884927
    Abstract: The present disclosure provides a heterogeneous Ziegler-Natta catalyst system to be used in the preparation of ultra-high molecular weight polymers (UHMWP). The system includes at least one procatalyst, at least one co-catalyst, at least one hydrocarbon medium and at least one external donor, wherein the ratio of elemental magnesium to elemental titanium to halide, in the procatalyst, is 1:1.3:3.7; the ratio of elemental aluminum, present in the co-catalyst to elemental titanium, present in the procatalyst, ranges between 6:1 and 12:1; and the ratio of elemental silicon, present in the external donor to elemental titanium, present in the procatalyst, ranges between 1:10 and 10:1. The present disclosure also provides a process for preparation of UHMWPE using the heterogeneous Ziegler-Natta catalyst system of the present disclosure.

  • Polymer composition and a process for preparing the same
    Patent number: 9512307
    Abstract: A polymer composition has homogenous dispersion of a first polymer with a second polymer. The first polymer includes but is not limited to ethylene based homopolymer and ethylene based copolymer. The second polymer has molecular weight higher than the molecular weight of the first polymer and heat of fusion greater than 200 J/g.
