Answer #1

N,N'-Methylenebisacrylamide (MBAm or MBAA[) is a cross-linking agent . [A cross-link is a bond that links one polymer chain to another]. Its molecular formula is C7H10N2O2

It is used during the formation of polymers such as polyacrylamide.

Bisacrylamide polymerizes with acrylamide and is capable of creating cross-links between polyacrylamide chains. Thus it creates a network of polyacrylamide rather than unconnected linear chains of polyacrylamide, and thereby helps in maintaining the firmness of polyacrylamide .

2. Nylon 6, 6 is formed by the process of polymerization condensation of hexamethylene diamine [NH2 - (CH2) 6 - NH2] and adipic acid [HOOC - (CH2) 4 - COOH] with a byproduct in the form of water. The polymerization reaction that occurs is as follows: nHOOC - (CH2) 4 - COOH + n H2N - (CH2) 6 - NH2 → [- OC - (CH2) 4 - CO - NH - (CH2) 6 - NH -]n + (2n - 1)...

4) If the number-average degree of polymerization for polystyrene obtained by the bulk polymerization of styrene at 60°C is 1000, what would be the number-average degree of polymerization if the polymerization were conducted in a 10% solution in toluene (900 g of toluene per 100 g of styrene) under otherwise identical conditions? The molecular weights of styrene and toluene are 104.12 and 92.15, respectively. Assume free-radical polymerizationa that includes chain-transfer termination, as well.
