Soluble Ladder Type of Poly (Silsesquioxanes) having Functional Groups,As technology develops, there is an ever-Increasing demand for materials that are resistant to various modes of degradation. Ladder polymers are therefore of particular interest since, theoretically, they possess increased resistance to any type of degradation as compared to conventional linear polymers..

1H NMR Studies on Conformation of Poly(Vinylidene Fluoride) in Solution and its Relation with Crystzation condition such as the species of precipitation solvent, the concentrations of polymer and the annealing tenperature in crystallization (1~5). These suggest that the conformations in solution-grown crystals are closely related to those in solution used for the growth of the crystal.

The Structures of Collagen,omponent of our skin and of the connective tissue holding different parts of our bodies together. There has been a large amount of research, by many good scientists, on the structures of collagen, but I am convinced that the structure patterns that have previously been proposed (including some propo

Head to Head Polymers,ds. Head to head polyolefins, polypropylene and polystyrene were synthesized by 1, 4 polymerization of 2, 3-dimethyl (or diphenyl) butadiene followed by catalytic hydrogenation with soluble catalyst (Co/Al) or by chemical reduction (K/ethanol)..Polyisobutylene of low molecular weight was synthesized

Polycondensation Reactions in the Presence of Polymer Matrices,e expected to interact with monomers or the resulting polyamides owing to hydrogen bonding or charge-transfer. It was found that the rate of polycondensation of dimethyl tartrate(DMT) with hexamethylenediamine(HMD) was enhanced by polymer matrices such as poly(vinyl pyrrolidone) (PVP), pullulan (pol
