It is disclosed that a saccharide-derived monomer in which polymerizable functional group is introduced into hydroxyl group or other functional group contained in a saccharide or a saccharide derivative compound and cyanoethyl group is introduced into all of or a part of the remaining hydroxyl group or other functional group.

Saccharide-derived monomer, method for manufacturing the same and highly-dielectric polymer consisting of the said monomer

Disclosed herein is fine inorganic particles-containing fiber which is characterized in that the fiber contains fine inorganic particles with an average particle size of not larger than 10 .mu.m and the fiber-forming polymer contains not less than 0.01 milliequivalent/gram of any of the polar groups consisting of sulfonic acid group, carboxyl group and phosphoric acid group.

Fine inorganic particles-containing fibers and method for forming the

Spherical resin particles having a sharp particle size distribution and a method for producing such particles are disclosed. Resin particles according to this invention contain at least a polyester polymer and a polymer formed from a polymerizable monomer, and have an average diameter (D) of 1 to 500 .mu.m. At least 70% by weight of the particles have a diameter in the range of 0.5 D to 2.0 D. Such resin particles can be produced by swelling polyester-containing seed particles with a polymerizable monomer and then polymerizing the polymerizable monomer in swelled seed particles.

Polymer particles and process for producing the same

Spherical resin particles in micron order with a narrow particle diameter distribution, methods for the production thereof and uses thereof are disclosed. Overcoming various problems comprised in the hitherto-known polymerization granulation methods, resin particles using a condensation polymer in micron order of the present invention having spherical form and narrow particle diameter distribution serve well for various applications.
