摘要:
A modified polymer includes a diene-based polymeric chain and at least one end terminated with a blocked isocyanate group. The blocked isocyanate group may be the reaction product of an isocyanate and a blocking agent, and the blocking agent is selected such that the modified polymer deblocks at temperatures of at least 100 °C. An aqueous emulsion of the modified polymer may be provided that may be surfactant-free. The emulsion may be combined with one or more latexes to provide a treatment solution for a fabric or fiber that does not require the use of resorcinol and formaldehyde. Once treated and dried, the fabric or fiber may be used to impart tensile strength to rubber products, such as tires, air springs, flexible couplings, power transmission belts, conveyor belts, and fluid routing hoses.

摘要:
The invention aims at providing a catalyst for polymerizing one or more polar unsaturated compounds into a (co)polymer which catalyst enables extremely efficient production of such (co)polymers closely controlled in number-average molecular weight with a closely controlled number of formed molecules, and (co)polymers obtained by using the catalyst. More specifically, the invention relates to a polymerization catalyst composition containing a composition comprising an organic-oxy salt compound (i.e., a salt of an organic oxy anion) and a hydroxy-carbonyl compound bearing in the molecule both an alcoholic hydroxyl group and a carbonyl group; polymerization of polar unsaturated compounds with the catalyst; and compositions containing the (co)polymers obtained by this polymerization, which are useful particularly as thermosetting powder coating materials excellent in performances.
摘要:
Polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions are useful in dispersing various compounds in a carrier liquid. The polycationic polymeric antimicrobial surfactant and polymeric biocompatible antimicrobial surfactant compositions employ polymers having both hydrophilic domains and hydrophobic domains so that the compositions can disperse particles such as polymer particles or droplets in a continuous phase as well as provide stable dispersions that have not been provided before. The antimicrobial properties of the compositions provide much-needed capabilities of fighting infectious agents such as bacteria and viruses in a wide spectrum of products such as paint, adhesives, and coatings. Methods of using these compositions as well as methods of making products using the compositions are disclosed.
