Polyolefin microstructural deconvolution methods: The good, the bad, and the ugly

چکیده
The deconvolution of the molecular weight distribution (MWD) polyolefins into Schultz–Flory most probable distributions has become standard method to identify number site types on multiple-site-type olefin polymerization catalysts such as Ziegler–Natta, Phillips, and some supported metallocenes. This been used quantify effect conditions catalyst formulations polyolefin MWD kinetics. Related methods have also developed deconvolute other microstructure features, chemical composition comonomer sequence length distributions. In this paper, I explain premises behind these models review publications in area, highlighting advantages, disadvantages, misuses methods. propose a revised formulation how model made with using ratio for propagation chain transfer frequencies. main objective overview article is highlight strengths, but show pitfalls,

Electronic mail has become the unexciting and mundane electronic communication medium we love to hate. It wasn’t always that way. Hate is a fairly recent emotion. Email has been with us in one form or another since the earliest days of computer networks and bulletin board services. From inauspicious beginnings, it became one of the three “killer apps,” along with Telnet and FTP, that gave the I...

This paper discusses the neo-logicist approach to the foundations of mathematics by highlighting an issue that arises from looking at the Bad Company objection from an epistemological perspective. For the most part, our issue is independent of the details of any resolution of the Bad Company objection and, as we will show, it concerns other foundational approaches in the philosophy of mathemati...

During the last several years, we have witnessed “the best of times and the worst of times” in the embryonic field of gene therapy. Rapid advances in human genomic sciences, the development of novel mouse models of human diseases, and the construction and characterization of new vector systems for in vivo gene transduction have significantly expanded the potential feasibility of human gene ther...

The present R graphics system was originally written as a placeholder, which could be replaced when a better alternative became available. This temporary solution has now become so entrenched that it is probably no longer possible to remove it. In this paper we will look at some of what is possible in the R graphics system, how it could be improved, and what might not be fixable. We will also l...
