Hyperbranched polymer, process for producing same, and composition

Provided is a hyperbranched polymer having such a backbone that is readily decomposable by an acid. The hyperbranched polymer is derived from, via reaction, monomers including a monomer (X) and a monomer (Y). The monomer (X) contains three or more hydroxy groups per molecule. The monomer (Y) contains two or more groups represented by General Formula (y) per molecule. The monomer (X) includes at least one compound selected from the group consisting of cyclodextrins, compounds represented by General Formula (I), pillararenes, compounds represented by General Formula (II), compounds represented by General Formula (III), and compounds represented by General Formula (IV). The monomer (Y) includes a compound represented by General Formula (1). General Formulae (y), (I), (II), (III), (IV), and (1) are expressed as follows: ##STR00001## ##STR00002##

Metathesis polymerization methods

The present disclosure is directed to methods of making a polymer, including exposing a reaction mixture including a strained cyclic unsaturated monomer and an organic initiator to a stimulus to provide an activated organic initiator, whereby the activated organic initiator is effective to polymerize the strained cyclic unsaturated monomer via a 4-membered carbocyclic intermediate to provide a polymer having constitutional units derived from the strained cyclic unsaturated monomer.

POLYMERS FROM BIS-ARYLCYCLOBUTENE GROUP CONTAINING MONOMERS THAT CURE THROUGH OTHER GROUPS AND METHODS FOR MAKING THE SAME

The present invention provides organic solvent soluble or aqueous alkali soluble polymer composition comprising, in copolymerized form, one or more bis-arylcyclobutene monomers and one or more olefin or dienophile group containing second monomers, wherein the polymer is substantially free of (unreacted) arylcyclobutene groups. The compositions cure by a separate from the B-staging reaction which consumes substantially all of the arylcyclobutene groups in the composition; and they cure at temperatures below the cure temperature of less than 210 C., preferably, less than 180 C. The polymer compositions find use in making films or coatings and are aqueous or organic solvent developable when used in photolithography. Methods for making the polymer compositions are also provided.

Synthesis and micro-/nanostructuring of surface-attached crosslinked antimicrobial and/or antibiofouling polymer networks

The present invention relates to substrates comprising a crosslinked network of covalently attached antimicrobial and/or antibiofouling polymers. The crosslinked network of antimicrobial and/or antibiofouling polymers acts highly efficiently against pathogens, e.g. bacteria and fungi. Both the antimicrobial and the antibiofouling cross-linked polymer networks are preferably better resistant to mechanical damage than simple surface-immobilized polymer monolayers. The antimicrobial and/or antibiofouling polymers of the crosslinked network are preferably obtained by ring opening metathesis polymerization (ROMP) and exhibit a molecular weight of preferably more than 30,000 or even 100,000 g mol.sup.1. The crosslinked network of antimicrobial and/or antibiofouling polymers is preferably covalently attached to the surface of a substrate, e.g. an implant, a medical device, medical equipment or a (tissue-supporting) biomaterial, etc. The present invention is also directed to uses of crosslinked networks of antimicrobial and/or antibiofouling polymers as defined herein, e.g. for coating a surface of a substrate, and to methods therefore.

The present disclosure provides the use of a biomolecule, flavin, appended to a polymerizable unit that can then be polymerized to form an electroactive active polymer. The polymer and the flavin unit are comprised of an organic material containing C, H, N, and O atoms. The electroactive functionality is related to the double bonds that are present in the flavin unit that are appended to a non-electroactive backbone. This appended unit is rendered insoluble in the electrolyte of the discussed secondary battery unit. Several different molecular structures are disclosed exhibiting efficacy as energy storage medium in energy storage devices. Compounds have also been synthesized from which these different energy storage molecular structures are produced.
