Effects of coupling agent on the rheological behavior and processability of polypropylene: Effects of coupling agent on the rheological behavior and processability of polypropylene. Dae Han, Chang; Kwack, Tae Hoon; Luo, Hong Lie (Dep. Chem. Eng., Polytech. Inst. New York, Brooklyn, NY 11201, USA). J. Appl. Polym. Sci., 29(8), 2599-615 (English) 1984. CODEN: JAPNAB. ISSN: 0021-8995. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 38 The effect of coupling agents on the rheol. behavior and processability of polypropylene (I) [9003-07-0] was studied. Each of 3 com. coupling agents (KR-TTS (isopropyltriisostearoyl titanate) [61417-49-0], A 1100 [919-30-2], and Y 9187 [2943-75-1]) was melt-blended with I. Melt blending was performed using a twin-screw compounding machine. The zero-shear viscosity of I was decreased by 1 order of magnitude after extrusion through the machine; coupling agents were added, I viscosity was higher than that of I without the coupling agents, undergoing the same deformation history through the machine. Independent measurements of the mol. wt. of the materials show that the wt.-av. mol. wt. (Mw) of the extruded I was 3.77 ′ 105, whereas the Mw of virgin I (for extrusion) was 4.80 ′ 105, indicating that considerable mol. degrdn. occurred during extrusion and the Mw of the I extruded with coupling agent was greater than that of I extruded without coupling agent. The mol. wt. measurement supports viscosity measurements of I studied with and without the coupling agent. Also measured were elongational viscosity of I with and without coupling agent, which was then correlated to the melt drawability of the materials studied.

DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Compns. useful as insulation on wire and cable comprise a water-curable silane-modified alkene-alkyl acrylate copolymer contg. a polysiloxane which are flame retardant without halogenated additives. Thus, 38.4 parts Et acrylate-ethylene copolymer [9010-86-0] and 0.59 part 1,2-dihydro-2,3,4-trimethylquinoline antioxidant were mixed at 170°, and 0.48 part octyltriethoxysilane [2943-75-1] was added. After 5 min, polysiloxane 0.96, tetraisopropyl titanate [546-68-9] 1.92, dibutyltin dilaurate 0.05, and Al(OH)3 57.6 parts were added. Samples from the compn. had Limiting O Index 30.
