tacticities of select polymers on their theta temperatures and

the unperturbed dimensions has also been reviewed [15,16].

The differences in the u temperatures of protiated and deu-

terated systems have been studied [16a,b].

This chapter presents a collection of theta temperatures

reported for various polymers, in Tables 15.1–15.11. In

cases where a number of authors have studied the same

polymer, the results are given in chronological order. This,

in a sense, serves to follow the progress in this area. The

solvents and the corresponding theta temperatures are

grouped together from the results of a particular author(s)

so that these would correspond to samples with the same

characteristics in terms of M

and its distribution.

In these tables, the polymer name is given in the first

column. The tacticities of the polymer studied, if reported by

the authors, are given either in terms of the diad fraction

or f

), or triad fractions (f

, f

mrþrm

, and f

). Here the

subscripts m and r refer to meso and racemic diads, respect-

ively (see Chapter 1 on Chain Structures for these defin-

itions). In Table 15.11, which is devoted to copolymers, the

TABLE 15.1. Poly(alkanes).
