Two polymers have similar solubility parameters,and can interact strongly by hydrogen bonding interaction. They are mixed together to form a blend. The blend may be described by which of the following statement?

		The blend is non-homogeneous and is characterized in differential scanning calorimetry (DSC) measurement as having one glass transition point (Tg)
		The blend is non-homogeneous and is characterized in differential scanning calorimetry (DSC) measurement as having two glass transition point (Tg)
		The blend is homogeneous ans characterized in differential scanning calorimetry (DSC) measurement as having two glass transition point (Tg)
		none of the above
