Introduction to Polymers
A Simple Scheme for Adhesion, and Five Adhesive Mechanisms
(TCW #1)
Why adhesives stick to substrates can be broken down into five,
non-independent, possibilities and these areexplained. Since most
modern adhesives are synthetic polymers, the parameters that govern their application asadhesives are briefly outlined here.

POLYMER FUNDAMENTALS
Mechanisms of Adhesion and Polymer Parameters

In much more detail, the factors of chemical structure, molecular weight, stereochemistry, chain architecture, andsolid state structure are explained as they apply to adhesion science.
Mechanical and Thermal Properties
Simple Mechanical Tests of Bulk Adhesives (TCW #3)
Independent of an adhesive joint, we can measure the behavior of bulk adhesives and learn much about thoseapplications for which they will be suitable. These test are described and interpreted for glassy, elastomeric andsemicrystalline systems.
DMA and Relaxations in Polymeric Adhesives (TCW #4)
Much of adhesive joint performance can be analyzed in terms of energy management and dissipation. So, for bulkpolymers we use dynamic mechanical tests to estimate this feature. Interpretation of these experiments is illustratedfor a variety of systems.

All adhesives and sealants that are processed as fluids exhibit complex flow behaviors. This lecture reviews basicfeatures of complex fluids that are common to melts, solutions, and suspensions that comprise many adhesives andsealants. Several rheological functions are defined and explained such as viscosity and the loss and storage moduli.Some of the most useful instrumental methods for measuring these functions are then reviewed. Finally, someimportant structure-rheology relationships for melts, solutions, and suspensions are discussed with a focus on howthese can be used in processing adhesives and sealants.
