Average sequence length mean distributions

The average sequence lengths can be readily determined from the mean of the distributions ... 

When measuring vinyl polymer tactlclty, one prefers the longest complete n-ad distribution available as well as the translated simplest comonomer distribution, possibly m versus r. An alternative exists to the m versus r distribution In the form of number average or mean sequence lengths. If any vinyl homopolymer Is viewed conceptually as a copolymer of meso and racemic dyads, mean sequence lengths can be determined for continuous runs of both meso and racemic configurations (32), that Is,... 

The sequence distributions are clearly non-Bernoulllan in this case although they could satisfy conformity to Markovian behavior as indicated by equations 11-13. The following average structure is suggested by these observed mean sequence lengths. 

Copolymers can vary in their average composition and mean monomeric unit sequence length, as well as in the distributions in composition and sequences. It is useful to consider sequences of polymers with a small number of different monomeric units (e.g., proteins). Since the determination of sequence is very specific of multipolymers with many different monomeric units, this will be discussed under the relevant polymer. 

Therefore, we conclude that for the designed copolymers, collapse occurs at a markedly higher kinetic rate, k 1 / ( 1/2) The kinetic properties are clearly related to the sequence distribution. Still it is possible to select champions from the protein-like fast folders. Who are those champions They normally have a larger mean length of hydrophobic and hydrophilic blocks, wider distribution of block length and the average hydrophobicity decreasing towards the chain ends. 

Now, it is well known that, according to the average length of sequences, copolymers have, at constant composition, different physical and mechanical properties. Then it does not seem advisable to characterize them by means of a quantity that is indissolubly bound to a particular mechanism of copolymer formation for example, if one takes into account, as Ham does [i], the effect of the penultimate units on chain growth, ri and V2 lose their usual meaning, but the copolymer properties still depend on the sequence distribution and need a different form of characterization. 

When we say These pdymers contain isotactic (or syndiotactic) stereoblocks we mean that equal diads are organized in sequences of average length longer than would be pr icted by a Bernoullian distribution.
