Abstract: The present invention discloses a modified polypropylene composition with higher flow activation energy and reduced necking in extrusion film/coat, wherein the composition comprises long chain branched polypropylene; a free radical initiator; a primary antioxidant; a secondary antioxidant; an acid neutralizer; and optionally a multifunctional monomer. Further the said composition of polypropylene shows higher sensitivity of viscosity to temperature, with improved stretchability.

Abstract: The present invention relates to a one step process for the palletization of poly lactic acid of molecular weight in the range of 6-8 lakhs without melt processing such that the pellets obtained exhibit minimal molecular weight reduction. The molecular weight of poly lactic acid (PLA) in the obtained pellets is retained in the range of 6-8 lakhs.

Abstract: The present invention relates to an etched optical fiber as force transducer with feedback control, with a force range of 1-108 pN and a displacement range of 10-105 nm with a spatial resolution of the order of tens of nanometers are accessible with the instrument. The sample deformation (evolution) can be imaged simultaneously with rheological measurements. The device is used to perform extension rheology of polymer melts, silk, or other bio-fluids at microscales, measure mechanical responses of living cells such as neurons, muscle cells, etc. It is also used as a passive probe for microscale force measurements and to investigate properties of active suspensions such as bacterial baths.
