    • It has been pointed out by DeGennes, that reptation may beimpaired by branches. This may account for the apparent requirement that a small amount of branching be present to allow amorphous PE to be formed, as noted by Cutter et al. (ref. 19). It is these observations that led us to suggest in the text that if a considerable amount of branching were present in PE that difficulty might be encountered in crystallizing such material with chain folding because of the retardation to reptation

    • Doubt has been expressed concerning whether ‘niches’ are favoured sites for the attachment of polymer stems on a growth front see, Otherwise, the belief that niches are active sites for the attachment of stems appears to be widely accepted. If niches were not operative on the substrate, neither the existence of the Regime I → II nor most especially the Regime II → III transition could be predicted or understood. In the light of this development, the experimental evidence cited by Wunderlich as disfavouring the niche concept should be reconsidered
