1 Beat the eggs in a large mixing bowl. 2  Melt the 2 tablespoons shortening, and add it and the sour cream to the eggs. 3  In another bowl, sift together 1 1/4 cups sugar, flour, cocoa and 1/4 teaspoon salt. 4  Add these dry ingredients to the egg mixture. 5  Stir the batter until smooth.
Natural polymers. Polymers are very common in nature; some of the most widespread naturally occurring substances are polymers. Starch and cellulose are examples. Green plants have the ability to take the simple sugar known as glucose and make very long chains containing many glucose units.atural polymers.

Monomers and Polymers. Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. All monomers have the capacity to form chemical bonds to at least two other monomer molecules. monomers.Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units.a polymer. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.eteropolymers are polymers composed of more than one kind of monomer. a polymer consisting of more than one type of monomer. Artificial Polymers and Special Properties. One of the first humans to discover, and make, an artificial polymer, was the German chemist Hans von Pechmann.
