Side-chain supramolecular polymers employing conformer independent triple hydrogen bonding arrays

Derivatives of thymine have been extensively used to promote supramolecular materials assembly. Such derivatives can be synthetically challenging to access and may be susceptible to degradation. The current article uses a conformer-independent acceptor-donor-acceptor array (ureidopyrimidine) which forms moderate affinity interactions with diamidopyridine derivatives to effect supramolecular blend formation between polystyrene and poly(methyl methacrylate) polymers obtained by RAFT which have been functionalized with the hydrogen bonding motifs

A Preliminary Investigation into the Effects of the Federal Override of State Usury Ceilings on the Supply of Mortgage Funds by FSLIC-Insured S&Ls in New York and New Jersey

Examined is the economic theory that restrictive usury ceilings reduce the supply of residential mortgage funds and tighten terms of the mortgage instrument. Studied are the mortgage policies adopted by New York and New Jersey FSLIC-insured S&Ls during periods when there were restrictive usury ceilings and when these usury ceilings were removed. The results clearly confirm the theory that effective elimination of usury ceilings increases the supply of mortgage funds and also liberalizes the terms of the mortgage instrument.
