    Abstract: The present invention provides a method of forming a chemical mechanical polishing pad, providing a tank with polymeric materials and a storage silo with microspheres. Further, the method includes the step of providing a curative storage tank with curing agents. Further, the method includes delivering the polymeric materials and the microspheres to a premix prep tank and forming a pre-mixture of the polymeric materials and the microspheres. The method further includes the step of recirculating the pre-mixture until a desired bulk density is reached. The method further provides the steps of delivering the pre-mixture to a premix run tank, forming a mixture of the pre-mixture and the curing agents, pouring the mixture into a mold and cutting the mold into the polishing pad.

    Abstract: A PROCESS FOR THE CONTINUOUS PERFORMANCE OF AN ANIONIC POLYMERIZATION LACTANS IS DISCLOSED. IN THE PROCESS CATALYSTS SUCH AS LACTAM ALKALI OR ALKALINE EARTH METAL COMPOUNDS AND ACTIVATORS SUCH AS ACYLATED LACTAMS OR ACYLATABLE COMPOUNDS ARE MIXED WITH MOLTEN LACTAM IN THE PRESENCE OF NITROGEN. THE PROCESS IS CHARACTERIZED BY THE FACT THAT SIMULTANEOUSLY ONE PORTION OF MOLTEN LACTAM IS MIXED WITH AN ACTIVATOR AND A SECOND PORTION IS MICE IXED WITH A CATALYST,IN EACH CASE WITH EXCLUSION OF OXYGEN AND CONTINUOUS NITROGEN ACTION ON THE TWO MELTS,BEFORE EVENTUALLY BEING METERED VIA A SYPHON-LIKE SPIRAL TUBE SYSTEM UNDER THE SAME TEMPERATURE ACTION AS THE MELTS TO A MIXING DEVICE INTO WHICH THE TWO SPIRAL TUBE SYSTEMS DISCHARGE WHEREBY POLYMERIZATION TAKES PLACE. ALSO DISCLOSED IS APPARATUS FOR USE IN THE DESCRIBED PROCESS CHARACTERIZED BY TWO FIRST CONTAINERS FOR PREPARING THE TWO LACTAM MELT PARTIAL QUANTITIVES TO WHICH IS CONNECTED IN EACH CASE A SECOND CONTAINER FOR A CATALYST OR AN ACTIVATOR WHICH VIA SYNCHRONOUSLY OPERATING LIQUID PUMPS ARE EACH CONNECTED WITH A SYPHON-LIKE SPIRAL TUBE SYSTEM LEADING TO A MIXING DEVICE, WHEREBY ALL CONTAINERS ARE SEALED IN AN AIR-TIGHT MANNER AND PUMPS AND SPIRAL TUBE SYSTEM ARE HEATABLE AND WHEREIN A NITROGEN FEED AND DRAIN SYSTEM AND A STIRRER ARE PROVIDED.

    Abstract: A pump/dispenser, ratioing/mixer dispenser apparatus and a method and apparatus for precision vacuum degassed dispensing of work liquids are presented. The pump/dispenser is a positive displacement high precision piston/cylinder constant flush type with piston smaller than chamber. The piston is advanced along its stroke in tiny repeatable adjustably programmable steps, the infinitely adjustable precision ratioing programmable mixing being provided when two such pumps are used. The vacuum degassed work liquids dispensing system features the creation and maintenance of a positive absolute pressure on the work liquid(s) when exiting the degassing chamber(s) to the dispensing outlet(s) whether moved along the flow path through the precision dispensing pump(s) or other types of pump(s). Available softwear and adjustable programmable precision hardwear of the system may be provided by a widely available personal computer. Further degassing is provided by dispensing in a vacuum.
