A number of extreme changes occur upon chemical crosslinking of polymers. Which one of the statements is not correct: (Choose from the following four possibilities)

		Increasing crosslink density: Increases rigidity which can give brittle polymers
		Crosslinking is frequently used to decrease the crystalline transition temperature Tm.
		In elastomers (rubbers) the crosslink density is low to allow large deformations
		One major effect is that soluble polymers are no longer soluble.
