摘要:
Disclosed are derivatives of isophorone diamine exhibiting a synergistic relationship with other commonly employed chain extenders offerings enhanced efficacy with regard to slowing of the polyurea elastomer cure profile, and processes employing their use. According to the invention, extensions of the gel-free and tack-free times are more readily achieved at lower loading levels for these chain extender blends than are afforded through the sole use of the individual molecules.
摘要:
The invention relates to crosslinked organopolysiloxanes which are linked by a polyether building block via the Si atoms, to emulsifier systems which have these crosslinked organopolysiloxanes, and also to cosmetic, dermatological or pharmaceutical formulations comprising a crosslinked organopolysiloxane or an emulsifier system comprising these.
摘要:
Fluorescent monomers are described and claimed which are synthesized by reacting a substituted or non-substituted naphthalic anhydride with an amine and with a moiety containing a polymerizable group. Such monomers are useful for the preparation of tagged treatment polymers. Such tagged treatment polymers are useful as scale inhibitors in industrial water systems.
