Here are described polymers comprising monomeric units from vinylimidazole derivatives and their use in electrode materials and/or electrolyte compositions, as well as their methods of preparation. Also described are electrode materials, electrodes, and electrochemical cells comprising the polymers and their use.
摘要:
Disclosed herein are polymer compositions useful for scale inhibiting applications. The polymer compositions include a plurality of monomers, which include at least one carboxylic acid and a sulfonated acid. The polymer compositions are used in polymer mixtures in water sources for inhibiting scale formation at relatively low dosages.

The present invention relates to a hair styling and restyling composition comprising a cosmetically acceptable pressure sensitive adhesive polymer with restyling performance and improved washout from hair, to a pressure sensitive adhesive polymer with glass transition temperatures of lower than –20°C, to a process for preparing said pressure sensitive adhesive polymer and to use of said pressure sensitive adhesive polymer for improving the restylability and washout behavior of a hair styling and restyling composition.
摘要:
Es werden Copolymere auf Basis von ungesättigten Mono- oder Dicarbonsäure-Derivaten, Oxyalkylenglykol-Alkenylethern sowie ggf. vinylischen Polyalkylenglykol- oder Ester-Verbindungen beschrieben sowie deren Verwendung als Zusatzmittel für wässrige Suspensionen auf Basis von mineralischen oder bituminösen Bindemitteln, insbesondere Zement, Gips, Kalk, Anhydrit, oder sonstige Calciumsulfat basierende Bindemittel sowie auf Basis von pulverförmigen Dispersionsbindemitteln. Die erfindungsgemäßen Copolymere verleihen den wässrigen Bindemittelsuspensionen eine sehr gute Dispergier- bzw. Verflüssigungswirkung bei gleichzeitiger ausgezeichneten Verarbeitungseigenschaften. Außerdem sind die erfindungsgemäß eingesetzten Oxyalkylenglykol-Alkenylether technisch relativ einfach sowie kostengünstig herzustellen und benötigen vergleichsweise niedrige Initiatorkonzentrationen bei der Copolymerisation.
摘要:
A nitrogen-containing ester derived from a carboxy-containing interpolymer having a reduced specific viscosity (RSV) of from about 0.05 to about 2, said interpolymer being derived from at least two monomers, (i) one of said monomers being at least one of an aliphatic olefin containing from 2 to about 30 carbon atoms and a vinyl aromatic monomer and (ii) the other of said monomers being at least one alpha, beta-unsaturated acylating agent, said ester being characterized by the presence within its polymeric structure of each of the following groups which are derived from the carboxy groups of said interpolymer: (A) from about 20 to about 70 mole % based on moles of carboxyl groups in said interpolymer, of ester groups containing from about 13 to about 19 carbon atoms; (B) from about 80 to about 30 mole %, based on moles of carboxyl groups in said interpolymer, of ester groups containing from about 8 to about 12 carbon atoms, optionally; (C) up to about 20 mole %, based on moles of carboxyl groups in said interpolymer, of ester groups containing from 2 to 7 carbon atoms; wherein from about 93 to about 97% of the carboxy groups derived from the carboxy-containing interpolymer are ester groups, the balance of the carboxy groups comprising residual carboxylic acid or anhydride groups which are then (D) reacted with at least one amino compound having an average of from 1 to about 1.1 primary or secondary amino groups, to convert from about 5 up to less than 50 % of the carboxylic acid or anhydride groups to carbonyl-amino groups, with the unreacted carboxylic acid or anhydride groups remaining as (E) residual carboxylic acid or anhydride groups. Additive concentrates and lubricating oil compositions are also disclosed.
摘要:
A web of superabsorbent polymer and fiber made by an in situ neutralization, wet-laid process, wherein the degree of neutralization of the superabsorbent polymer is partial, preferably less than about 80 mol %. The web exhibits an excellent centrifuge retention capacity property, as compared to prior webs of superabsorbent polymer and cellulosic fiber made by in situ neutralization, wherein the degree of neutralization is total, such as 100 mol % or more.
