The up shift of the spectra comes from the weakening of hydrogen bond and increase in the heterogeneity of system that determines an increase of the scattered radiation as result of increasing in the mobility of alkylene
The composition is comprised of ethoxylated alcohol; polymeric alkylene
oxide block copolymer; oxygenated hydrocarbon co-hardening agent.
Absorption bands with the following wave numbers were observed in the IR spectra of the obtained compounds (Figure 3(a)): nC=N = 1600-1630 [cm.sup.-1], indicating the presence of imidazoline cycles; nC=0 = 1740-1745 [cm.sup.-1], n-N(CO)R = 1660 [cm.sup.-1], and nCN = 1260-1300 [cm.sup.-1] can be related to alkanoylamide structures; [delta][(C[H.sub.2]).sub.x] = 720 [cm.sup.-1]-- corresponds to pendular oscillation of alkylene
structure in a chain .
Duke developed ozone reactive polymers based on substituted or unsubstituted alkylene
polymers and their salts.
Synthesis and comparative biodegradability studies of three poly(alkylene
The stoichiometry favors the formation of long sequences of tetramethylene terephthalate (4GT) units in block copolymers consisting of crystallizable 4GT hard segments and amorphous elastomeric poly(alkylene
ether terephthalate) soft segments (refs.
During the drafting process, describing and protecting alternatives is where the inventor's knowledge of the invention is critical--what is the length of the alkylene
chain such that the surfactant still retains activity?
