Abstract: Blocky chlorinated polyolefins are disclosed as compatibilizers of PVC and/or CPVC resins with polyolefin elastomers. The blocky chlorinated polyolefins facilitate the dispersion of the elastomers as a dispersed phase with the proper size for impact modification of the PVC and/or CPVC. The blocky chlorinated polyolefin provides better adhesion between the elastomer and the PVC and/or CPVC providing better physical properties such as impact strength as measured by Notched Izod and variable height impact testing (VHIT) than did the randomly chlorinated polyolefins, often used as processing aids and as impact modifiers in PVC or CPVC. The differences in properties achieved with blocky chlorinated polyolefins versus randomly chlorinated polyolefins are attributed to the individual blocks of the blocky polyolefin being compatible (and/or co-crystalizable) with either the polyolefin elastomer or the PVC/CPVC resulting in better adhesion between phases.

Abstract: A low molecular weight polyether oligomer is modified with a salt during chain extending reaction of the polyether oligomer to form electrostatic dissipative polymer products such as polyurethanes, polyether amide block copolymers and polyether-ester block copolymers. The reaction product polymers exhibit relatively low surface and volume resistivities, and static decay times which are not too fast or too slow, yet are free of excessive amounts of extractable anions, particularly chlorine, nitrate, phosphate and sulfate. The electrostatic dissipative polymers can be blended with a variety of base polymers to form plastic alloys, which in turn can be utilized to form articles useful in the manufacture of electrostatic sensitive electronic devices.
Abstract: The present invention relates to a radiation sensitive photoresist composition comprising a photoacid initiator and a polycyclic polymer comprising repeating units that contain pendant acid labile groups. Upon exposure to an imaging radiation source the photoacid initiator generates an acid which cleaves the pendant acid labile groups effecting a polarity change in the polymer. The polymer is rendered soluble in an aqueous base in the areas exposed to the imaging source.

Abstract: A self-propelled model vehicle adapted for use on a closed loop raceway having a guide slot coextensive therewith is provided with a guide arm including a downwardly depending guide pin that engages with the guide slot of the raceway. The guide slot defines the boundary between two adjacent lanes of the raceway. The guide arm is controlled by a motor for lateral movement. The lateral movement of the guide arm forces the guide pin against a side of the guide slot to effect the lateral displacement of the model vehicle into the adjacent lane of the raceway. Also provided is a raceway layout comprising a plurality of modular sections each section having an integral guide slot therein. In the assembled mode the guide slot defines a closed loop guide way for engaging a slot car.

Abstract: Acrylate monomers such as methyl methacrylate, or other suitable monomers such as lactams, lactones, or acrylamides, are polymerized by reaction injection molding (RIM) utilizing a combination of organo group-4 catalysts, e.g., a neutral organo catalyst and a cationic organo catalyst. Preferably a Lewis acid is utilized which reacts with the neutral organo catalyst and forms in situ the cationic organo catalyst. Significant exotherms are rapidly generated and result in short cure times and typically in high conversions of at least 95 percent by weight of the monomer. The catalysts of the present invention give good control of tacticity and thus high Tg polymers such as syndiotactic methyl methacrylate can be produced.
