Preparation of Exemplary and Conventional Resins
Exemplary resins created by the invention described above are described below in the various examples. The materials and products described in the examples are characterized by a number of standard techniques. The molecular weight of each polymer was determined via gel permeation chromatography (“GPC”) techniques using tetrahydrofuran (“THF”) as eluent and poly(styrene) standards. The poly(styrene) standards employed are presently available from Polymer Laboratories Limited (Church Stretton, Great Britain) and are further characterized as having number average molecular weights of 2,250,000; 1,030,000; 570,000; 156,000; 66,000; 28,500; 9,200; 3,250; and 1,250. Acid numbers were determined by titration with a standardized base and are defined as the number of milligrams of potassium hydroxide needed to neutralize one gram of polymer. Viscosity was measured using a Brookfield viscometer available from Brookfield Engineering Laboratorie...
