Preferably, the resole also has a number average molecular weight greater than 350 and a dispersivity greater than about 1.7. Phenol formaldehyde r...

Bead-form expandable styrene polymers are obtained by suspension polymerization of styrene with addition of from 1 to 10% by weight of C3- to C6-hydrocarbons as blowing agents and, if desired, customary additives, where (a) the polymerization is initiated by rapidly heating the polymerization batch to form 80 DEG to 90 DEG C. within a maximum of 2 hours, (b) subsequently allowing the reaction te...

This invention relates to novel blowing agents comprising a blend of (A) perfluoro- or partially fluorinated-(cyclo)alkanes and (B) one or more of hydrogenated chlorofluorocarbons, hydrogenated fluorocarbons and a low boiling (cyclo)alkane. These blowing agents perform as well as the conventionally used CFC's but are user friendly and do not have the adverse effect of depletion of the ozone layer....

PURPOSE:To prevent the deviation of the resistance value of a resistance film from a specific value with lapse of time caused by an external factor by connecting a plurality of resistance films in parallel between a pair of beltlike conductor films and coating the resistance films with protective films, and then, cutting the resistance films by trimming them one by one. CONSTITUTION:A plurality of...

A method is disclosed for forming a capacitor on a semiconductor wafer. A first electrically conductive layer is applied atop the wafer and engages exposed active areas. A first dielectric layer is next applied. The first dielectric and conductive layers are then patterned to define an outline for the lower capacitor plate. A second dielectric layer, having an etch rate which is slower than the fi...
