Abstract

Dynamic-mechanical and fracture properties and proton-enhanced, magic angle spinning¹³C NMR time constants for polymers of the CH₂=C(CH3)CO(OCH2CH2)_xOCOC(CH₃)=CH2 series (x = 1 to jc = 22) and poly[tetrakis(ethylene glycol) diacrylate] have been measured. The effects of increasing length of the soft oxyethylene chain, Jc, undercure (x = 1–4), and oxyethylene crystallization (x = 22) were observed. The results are interpreted in terms of the contributions of components of group motion to the cooperative motion of segments of the network which control the response to a macroscopic deformation.
