Abstract
1,054,171. Polylactam compositions. POLYMER PROCESSES Inc. Feb. 19, 1964 [Feb. 27, 1963], No. 6932/64. Headings C3C and C3R. Hollow spherical particles of 30 to 300 microns in diameter are uniformly dispersed in polylactam by incorporating the particles in the monomeric lactam which is then polymerized by the low temperature anionic polymerization process. The particles may be made of phenol- or urea-formaldehyde resin or of glass. Several C 6 and higher lactams are specified.
