WO2018191186A1 Functionalized resin having a polar
Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that

characteristics such as good processing safety, a broad vulcanization plateau and optimum cross link density as well as desired reversion delay that they offer. The Primary Accelerators are used at 0.5 to 1.5 phr dosages in most rubber compounds.
The substitution of 3 phr ATH by 3 phr MLG resulted in the lowest value of THE, indicating that MLG, CB, and ATH showed good synergistic tendencies in this formulation. The effective heat of combustion (EHC) is the ratio of THE to total mass loss and is an indicator for gas phase activity ( 54 ), particularly flame poisoning.

- Is diphenylguanidine a tire wear product?
- Diphenylguanidine, a tire wear product, is present widely in human urine. 1. Introduction
- What is DPG & TPG?
- 1. Introduction 2. Materials and Methods 3. Results and Discussion 1,3-Diphenylguanidine (DPG), 1,3-di-o-tolylguanidine (DTG), and 1,2,3-triphenylguanidine (TPG) are rubber additives widely present in the indoor environment. Nevertheless, little is known about their human exposure.
- How common is DPG in human urine?
- The validated method was applied in the measurement of DPG, DTG, and TPG in real human urine samples, which revealed the occurrence of DPG in children’s urine samples (n = 15) with a detection frequency of 73% and at a median concentration of 0.05 ng/mL. DPG was found in 20% of adults’ urine samples (n = 20).
- Is DPG a metabolite?
- Furthermore, ∼28% of DPG excreted in urine was present as the parent compound, whereas the remainder was in the form of metabolites. 24 Nevertheless, metabolites of DPG were not identified, and further studies are warranted on this regard. Our study provides evidence of exposure to DPG and DTG in humans.
