摘要:
The invention relates to a water based polymer composition comprising a biopolymer and a synthetic polymer resin. The biopolymer results from a mechanical thermoplastic processing of a polysaccharide and/or protein starting material using shear forces in the presence of a crosslinking agent. The synthetic polymer resin consists of a water based hydrophilic resin and/or hydrophilic/hydrophobic resin. These compositions have a good storage stability. They are intended for the production of coatings with fair properties.
摘要:
A glass or pretreated meltblown fiber having a cationically charged coating thereon, the coating including a functionalized cationically charged, silicon containing carbohydrate polymer crosslinkable by heat, in which the functionalized cationic polymer has been crosslinked by heat after being coated onto the glass fiber. Also provided is a fibrous filter including a fibrous filter media having a cationically charged coating thereon, the coating including a functionalized cationic polymer crosslinkable by heat, in which the functionalized cationic polymer has been crosslinked by heat after being coated onto the fibers. Further provided is a method of preparing a fibrous filter. The method involves providing a fibrous filter which includes glass fibers or pretreated nonwoven fibers, passing a solution of a functionalized cationic starch polymer crosslinkable by heat through a fibrous filter under conditions sufficient to substantially coat the fibers with the functionalized cationic polymer, and treating the resulting coated fibrous filter with heat at a temperature and for a time sufficient to crosslink the functionalized cationic polymer present on the glass fibers.
