  • Use of organomodified siloxanes for surface modification of polyolefins
    Patent number: 7105233
    Abstract: The invention provides for the use of organomodified polysiloxanes of the general formula (I) in which R1 independently at each occurrence is an aliphatic or aromatic C1-20 hydrocarbon radical, R2, R2* independently of one another are R1 or are aliphatic, saturated or unsaturated C1-60 hydrocarbon radicals, optionally containing functional groups, a=1 to 500, preferably <100, in particular 5 to 50, b=0 to 50, preferably <20, in particular <10, c=0 to 50, preferably 0 to 10, in particular 0 as additives for surface enhancement in polyolefins.

  • Preparation of nondusting free-flowing pigment concentrates
    Patent number: 6743835
    Abstract: The invention relates to a process for preparing nondusting free-flowing pigment concentrates with removal of the water from pigment suspensions comprising polymers and dispersants in a fluidized bed drier. The resulting bead-form pigment concentrates are nondusting and readily free-flowing. The invention further embraces the use of pigment concentrates prepared in this way for coloring plastics and polymers.
