n honor of Raymond F. Boyer on the occasion of his 65th birthday and retirement from Dow. The topic of that first Boyer symposium dealt with an area of interest to Boyer, namely, polymer transitions and relaxations. One decade later, after ten years of additional fruitful scientific endeavor at MMI,预兆好 发表于 2025-3-28 23:23:27

Interim Report on the Thermoreversible Gelation of Polymershas been stimulated as the implications for both the solution and solid states have been recognized. The early interest and subsequent contributions of Dr. Raymond F. Boyer makes this a particularly timely occasion for this review.wangle 发表于 2025-3-29 13:47:42
Pellet Boundary Reformation in Reheated Polystyrene Moldings(molecular weight dependent) demonstrate definite signs of pellet boundary reformation upon reheat while those molded above this temperature do not. In most cases, this cutoff temperature is consistent with the .. transition temperature as indicated by DSC.一个搅动不安 发表于 2025-3-29 18:37:00

Interrelationships Between Molecular and Physical Structure in Amorphous Polymersxyl methacrylate), and .-butyl-substituted styrene polymers have been obtained. All show one or more scattering peaks at spacings greater than that of the van der Waals packing of atoms. The behavior of these peaks with change in chemical structure is in accord with our earlier studies of acrylate aanniversary 发表于 2025-3-30 02:27:19
