Abstract Adhesion between rubber and brass-coated steel cords is enhanced by using resins as adhesion promoters. Experiments were carried out using a squalene liquid rubber modeling approach to study the effect of resins on the chemistry of the vulcanization reaction. The formation of new intermediates during vulcanization and changes in chemical concentrations with reaction time was studied using Gel Permeation Chromatography (GPC) analysis of the reacted squalene mixtures. Also, the effect of presence of resins on the surface of sulfidized brass cords was studied by analyzing the adhesion layer's elemental composition using the Electron Dispersive X-ray Spectroscopy (EDX) and Secondary Ion Mass Spectrometry (SIMS) characterization techniques. The changes in surface morphology of the adhesion layer with reaction time was noted by taking micrographs using the Scanning Electron Microscopy (SEM) technique. In this paper, a new mechanism is proposed for the role of resins in the improvement of initial and aged adhesion performance between rubber and brass-coated steel tire cords.

ABSTRACT Protein modification by SUMO conjugation has emerged to be an important regulatory event. Recently, the mechanisms through which SUMO elicits its effects on target proteins have been elucidated. One of these is the noncovalent association between SUMO and coregulatory proteins via SUMO interaction motifs (SIMs). We therefore searched for additional binding proteins to elucidate how SUMO acts as a signal to potentiate novel noncovalent interactions with SUMO-binding proteins. We identified an E3 ligase, Pc2, as a SUMO-binding protein with two functionally distinct SIMs. Here, we focus on the role of SIM2 and demonstrate that it is crucial for many of the documented Pc2 functions, which converge on determining its E3 ligase activity. One role of SUMO binding in this context is the subnuclear partitioning of the active form of Ubc9 (SUMO∼Ubc9) by Pc2. The significance of the SIM2-dependent functions of Pc2 is demonstrated in the control of the precise expression of lineage-specific genes during embryonic stem cell differentiation.
