The sequence distribution of the hydrophobic monomers in the copolymers was controlled by varying the number of
hydrophobes per micelles, [N.sub.H], and it was assumed that the
hydrophobe content corresponds to the initial feed composition.
The concentration of AT
hydrophobes in a coating is low and would not promote a significant viscosity increase without interactions with other components in the coating.
With the [C.sub.18][H.sub.37](EO)[.sub.100] large
hydrophobe, an additional viscosity synergy is possible, as observed with larger hydrophobic HEUR thickeners.
(3-5) HASE thickeners are based on a polyelectrolyte backbone, usually methacrylic acid (MAA) and ethylacrylate (EA) copolymer, with pendant
hydrophobes (i.e.,
hydrophobes that are attached to the backbone with polyethylene oxide chains).
(14) The reciprocal of [tau] can then be approximated by the
hydrophobe dissociation rate, [[beta].sub.0], characterized by a bonding potential, [E.sub.m],

The
hydrophobe content was limited to 1 mol% and the incorporation level, determined by [sup.1]H-NMR spectroscopy, was close to the alimentation monomer feed.

Hydrophobe," Nature Structural Biology 1 (1994): 287-92; I.
The very fact they got me through the basic scuba-diving certificate is something of an achievement for such a
hydrophobe.
The alkyl functionality also acts as a
hydrophobe to reduce water absorption.
The reactions were maintained at their respective temperatures until the
hydrophobe solids reached approximately 23 percent, which corresponded to a water tolerance (WT) of approximately 200 percent.
In "Ithaca," Stephen declines Bloom's invitation to wash his hands, insisting he is a "
hydrophobe" (17.237), and the overly meticulous voice of the "Ithaca" narrator echoes Stephen's distaste for water, declaring an "incompatibility of aquacity with the erratic originality of genius" (17.247).
