Answer to Question 1

In general, as molecular weight increases, melt index will decrease. This is not always true from one polymer type to another, but is generally true within a particular polymer type. This relationship exists because the melt index measures the ease with which a polymer is melted. Melting is generally easier

Answer to Question 2

A copolymer is formed when more monomers are mixed together than are required for normal homopolymer formation. For addition polymerization this means that two different monomer types are required. For condensation polymerization three different monomer types are required. When these monomers are mixed, the resultant polymer has some of each of the monomers within it. These monomers can be arranged in four different patterns. The properties of the copolymer are normally intermediate between the properties of the homopolymers that would have been formed from pure, single-type monomers.
