Kurt W. Kohnthe most part, only polymers which are of commercial significance are considered and the primary aim of the book is to relate theoretical aspects to industrial practice. The book is mainly intended for use by students in technical institutions and universities who are specializing in polymer science

B. A. Newtonn 4.1 deals with the oscillation of superlinear equations with sign changing coefficients. Here, first we shall discuss some results which involve integrals and weighted integrals of the alternating coefficients, and then provide several criteria which use average behaviors of these integrals.

Fred E. Hahned discipline, turning more towards nonlinear and functional differential equations. Oscillation theory flows along two main streams. The first aims to study prop erties which are common to all linear differential equations. The other restricts its area of interest to certain families of equations
