The Problem

Introduction

The traditional philosophy that a college-or a university is an exclusive institution in which only highly selected individuals receive a concentrated training in the traditional liberal arts no longer exists. In America, for instance, as early as 1870, Harvard, the colonial college with a narrow curriculum, was transformed rather rapidly into a modern university with many new subjects and the elective system (Garrett, 1949). Also, since 1642, when the first entrance requirements were instituted for American higher education, a continuing debate has developed over what constitutes a sound curriculum for education. There are those who …

Synthesis And Analysis Of Dimers Of Alpha-Methylstyrene, Bhadreshkumar J. Mehta Aug 1975

Synthesis And Analysis Of Dimers Of Alpha-Methylstyrene, Bhadreshkumar J. Mehta

Masters Theses

Introduction

The heat of polymerization ∆Hp, of Alpha-methylstyrene (AMS) has been a source of study for many years. The structure of AMS is shown in Figure 1.

Roberts and Jessup carried out the first quantitative work to determine ∆Hp if AMS.¹ Their data displayed a ∆Hp dependence on the degree of polymerization, DP. Several other reports were also published with new values for ∆Hp and new explanations for the apparent DP dependence.^{2, 3, 4, 5.}

Samples of dimers of AMS have been prepared by various workers.^{6, 7, 8} The reactions were mostly carried out by using sulfuric …
