Abstract:
An oral composition and method for use thereof, comprising in an orally acceptable vehicle, an effective antiplaque amount of a noncationic antibacterial agent, and an anionic copolymer formed from monomers of which about 40 to about 90 % by weight are hydrophilic type capable of attachment to oral surfaces and about 10 to about 60 % by weight are of a hydrophobic type; such oral composition being effective in increasing the uptake of the antibacterial compound to dental tissue so as to enhance the therapeutic efficacy of the administered antibacterial compound.
Abstract:
The invention relates to the use of copolymers as gas hydrate inhibitors, whereby these copolymers are synthesized from: 40 to 99.5 % by weight of at least one ethylenically unsaturated cyclic lactam A; 0.5 to 60 % by weight of monomers B having a solubility in water of less than 10 parts by weight of monomers in 100 parts by weight of water, and; 0 to 50 % by weight of other monomers C.
Abstract:
The invention relates to a method for producing polymer solutions and/or polymer dispersions by means of radical polymerization, and to the use of the produced polymers, in particular, as g as hydrate inhibitors.
