The kinetics of irreversible reactions between polymer chains of different molecular weights are studied, with emphasis on the case of highly reactive end groups. We calculate the rate constant k(N, M ) for reaction between chains of lengths N a n d M respectively, in dilute and semi-dilute solution
## Abstract Much of the theory of gravity sedimentation has been based on the work of Coe and Clevenger (1916) and Kynch (1952). They provided methods for obtaining rates of sedimentation in batch, static tests which are presently used for design of continuous thickeners. Kynch assumed that a first
The changes in molecular mass distribution (MMD) after adsorption from solution in concentration regions below and above the critical concentration of overlapping have been studied for various polymers and their mixtures. It was found that the formation of entanglements in both binary and ternary so
