The Polyamines of GroupVA are synthesized under low yield moderate to high molecular weight employing the commercially available reactants and the interfacial polycondensation system. The IR spectroscopy determines the formation of bands characteristic to M-N bonds. Whereas MALDI MS determines the ion fragments to three units long with isotopic abundance results showing antimony in the triphenylantimony-derived clusters. The absence of the histamine ring proton in Nuclear magnetic resonance is c...

The Committee on Polymer Education (PolyEd) had its initial planning meeting in 1974. The Intersociety Polymer Education Council (IPEC) has been active since 1990 as an outgrowth of PolyEd. Because of the activities of PolyEd and IPEC, basic polymer concepts have become a required part of undergraduate education and a more common topic in the curriculum for K–12 students. A brief history of polymer education is given. The current and future activities of PolyEd and IPEC are described.

ABSTRACTPolyesters were formed from the reaction of the salt of camphoric acid and Group IVB metallocene dichlorides using the interfacial polycondenzation process. The polyesters were formed in good yields with moderate chain lengths. Fourier transform infrared spectroscopy shows bands characteristic of the presence of both reactants with new bands characteristic of the formation of the M‒O and M–O(CO) linkage present. The polymers largely exist in a bridging geometry of the carbonyl groups abo...

ABSTRACTWe describe the initial synthesis of DMSO and water-soluble titanocene polyethers through reaction of the titanocene dichloride and various poly(ethylene glycols) employing commercially available reactants. Infrared, proton NMR, and MALDI MS results are consistent with the titanocene-containing polyether structure. The materials are polymeric with chain lengths ranging from 1500 to 4. They exhibit good inhibition of a variety of cancer cell lines including two pancreatic cancer cell line...

ABSTRACTPoly(ether esters) are rapidly synthesized in moderate yield employing the interfacial polycondensation reaction system from the reaction of alpha-cyano-4-hydroxycinnamic acid and Group IVB metallocenes. The products are high polymers. Infrared spectroscopy shows the formation of new bands derived from the M-O and M-O(CO) linkages. It also shows that the products exist as alternating M-O and M-O(CO) linkages. The products show outstanding inhibition of a variety of cancer cell lines incl...

ABSTRACTPolymers derived from reacting Group IVB metallocene dihalides and the matrix alpha-cyano-4-hydroxycinnamic acid act as their own matrix agent when performing MALDI MS. Ion fragments containing two repeat units and greater are formed. The results are similar to those obtained employing graphite as the matrix material. The advantage of employing graphite as a comparative standard is that non-interfering ion fragment clusters are not produced by graphite. This is the second report of the i...

ABSTRACTA wide variety of organotin polyethers derived from the interfacial polymerization of dibutyltin dichloride and non-cancer inhibitory diols show decent to good inhibition of two human pancreatic cancer cell lines. In view of the general lack of ability of tested compounds to inhibit pancreatic cancer cell lines, this is significant. These cell lines are the AsPC-1 pancreatic cancer cell line which is an adenocarcinoma pancreatic cell line and the PANC-1 pancreatic cancer cell line which ...

The efforts described in this article are aimed at designing organotin polymers that control the growth of breast cancer and to identify structure/property relationships that assist in this goal. The growth of MCF-7 and MDA-MB-231 breast cancer cell lines is inhibited employing a wide range of organotin condensation polymers. The EC50 values are primarily dependent on the nature of the Lewis base but the CI50 is dependent on both the nature of the Lewis base and Lewis acid. A number of products ...

Suitable structure characterization is assisted through the use of mass spectrometry. Polymer fragmentation can be achieved in many ways including application of heat and ionizing radiation. MALDI MS allows routine analysis of polymers allowing identification of several repeat units. Graphite as a matrix allows higher mass ions to be created with less interfering ion fragments formed in comparison to more utilized matrix materials.
