maleated, etc. The epoxidized and maleated forms are also commercial products. All these materials are available to the rubber chemist and compounder, but the variety of materials can create confusion and uncertainty in their use. It is the purpose of this paper to partially clarify this situation. Liquid Polybutadiene Resins

In this work, a twostep treatment method was designed to prepare the modified AF, and a flexible interface layer between rubber and AF was built. AF was pretreated by a acid (LiCl) and then coated with low molecularweight maleated polybutadiene liquid (MLPB) or butadiene vinylpyridine latex (VPL) rubber.

Poly bd. Poly bd ® resins are low molecular weight, hydroxylterminated homopolymers of butadiene. These hydroxylterminated polybutadiene (HTPB) resins are characterized by low volatiles content, low glass transition temperatures, excellent hydrophobicity and a highly reactive functionality.
The effectiveness of the solid phase modified maleated polypropylene (MPP) as interphase modifier has been documented by comparing the properties of calcium carbonate filled polypropylene composites (PPCaCO 3) treated with solid phase modified MPP with that of the melt phase modified MPP treated composites. The solidphase ...
In the present study, composites of watersoluble polyurethane/calcium carbonate (CaCO3) were prepared from a soft segment of hydroxylterminated polybutadiene (HTPB) and polyethylene glycol (PEG, average molecular weight = 4000) with aliphatic diisocyanates. The functionality of CaCO3 particles was modified using aminopropyltriethoxysilane (APTES), and was confirmed by Fourier .
polybutadiene. Pure SEBS (curve a) shows stress–strain curves with all regions. The stress in the first and second regions is lowest among the others. On the other hand, stress in the third region reached a maximum value of almost 30 MPa. Addition of Conex fibre increases the stress in the first and second regions in all specimens. At Conex

Preparation of aqueous maleated shellac (MS) solution The maleated shellac samples were prepared by treatment of shellac with maleic anhydride method reported in our earlier communication 14. The process is as follow: A solution of shellac (40 g) in tetrydrofuran (THF) (150 mL), various proportions (10–30% wt of shellac) of
Polypropylene/calcium carbonate nanocomposites – effects of processing techniques and maleated polypropylene compatibiliser M. Y. A. Fuad1*, H. Hanim 1, R. Zarina, ... The surface of the NPCC filler is usually treated with fatty acids such as stearic acid, to modify the filler surface to .
A comparative study of the mechanical performance of PP and PP/PPgM blends reinforced with carbon fibre (CF) obtained by two different moulding techniques is presented. Three filler contents were used for fabricating the composites: 1, 3, and 5 pph (parts per hundred). The crystallisation behaviour of the composites was studied by differential scanning calorimetry.
Novatec* F additive is a maleated rosin polymer/glycol ether used as a fluid ... Treatment levels required depend on the desired filtration control, the brine ratio and density of the drilling fluid but will typically be in the range of to gal/bbl (8 to 20 L/m³). Pilot testing to determine necessary concentration is recommended.

treatment applications, the alkoxy groups of the trialkoxysilanes are hydrolyzed to form silanolcontaining species . Reaction of these silanes involves four steps . Initially, hydrolysis of the three labile groups occurs . Condensation to oligomers follows . The oligomers then hydrogen bond with OH groups of the substrate . Finally, during
Two phase structures were found: (1) treated calcium carbonate contributes to form the coreshell structure (2) nontreated calcium carbonate builds fillernetwork structure for the two POE.
Maleinization treatment through esterification with maleic anhydride is one of the modification route [2,6,7]. Maleated castor oil (MACO) is produced by esterification reaction of castor oil with maleic anhydride (M). Since esterification is an equilibrium reaction, thus high reaction yield can be
