摘要： Improving polyethylene film properties may be accomplished by measuring the specific energy input (SEI) to the extruder and then adjusting a process parameter in response to a change in the SEI and/or by introducing both a free radical initiator and an alkali earth metal stearate into the polymerization. Alternatively or in addition thereto, selecting the optimum free radical initiator for a particular polyethylene resin polymerized in the presence of a selected catalyst between two resin properties may be accomplished by examining the ratio of: % ⁢ ⁢ variation ⁢ ⁢ in ⁢ ⁢ a ⁢ ⁢ first ⁢ ⁢ property % ⁢ ⁢ variation ⁢ ⁢ in ⁢ ⁢ a ⁢ ⁢ second ⁢ ⁢ property of polyethylene resins individually made with each free radical initiator under consideration. The free radical initiator may be oxygen, peroxides, peroxyketals, peroxyesters, and/or dialkyl peroxides.

摘要： It has been discovered that certain compounds serve as particle size regulators when employed together with peroxide initiators for the polymerization of vinylaromatic monomers in the presence of diene polymers. Suitable compounds that can control particle size include, but are not necessarily limited to, cobalt naphthenate, zinc naphthenate, iron octoate, calcium octoate, zinc octoate, zinc neodecanoate, potassium octoate, copper naphthenate, calcium versalate, and the like. Use of these metal carboxylates when vinylaromatic monomers are polymerized in the presence of polybutadienes and peroxide initiators results in reduced polybutadiene particles. Grafting and morphology characteristics may also be improved.

摘要： It has been discovered that improved polystyrene products may be obtained by polymerizing styrene in the presence of at least one multifunctional initiator, at least one chain transfer agent, and at least one cross-linking agent. The presence of the multifunctional initiator tends to cause more branched structures in the polystyrene. A mathematical model that helps optimize the levels of these additives for given molecular weights, melt flow indices (MFIs) and zero shear viscosities (η0) has also been discovered.

摘要： It has been discovered that the melt instability of styrenic polymers, particularly high impact polystyrene (HIPS) can be reduced or eliminated by the blending therewith of a relatively high melt flow index (MFI) material, such as polystyrene homopolymer. Draw resonance of the melt blend can also be reduced by this method, thereby improving melt processing of these materials. A method to measure melt instability of drawn materials is also discussed.

摘要： The present invention provides a method for preparing an asphalt and thermoplastic elastomer composition. The process comprises preparing a crosslinking elastomer concentrate that is added to a heated asphalt cut in a stirred tank and then aged to improve SHRP high temperature grading. The crosslinking elastomer concentrate is prepared by adding thermoplastic elastomer and crosslinking agents to a suitable carrier oil, preferably an aromatic oil such as Hydrolene H series. This concentrate is maintained at a temperature that promotes association between the crosslinking agents and the elastomer for a time sufficient for association to substantially complete. In one embodiment, the associating time is in excess of 2 hours up to 24 hours. The asphalt is heated to a temperature sufficient to allow the stirring of the asphalt in the tank. The crosslinking thermoplastic elastomer concentrate is added to the asphalt while continuing to stir the asphalt. The mixture is stirred at a speed and for a period of time sufficient to increase the distribution of the elastomer into the asphalt. Stirring is continued for a period of time sufficient to improve the distribution of the crosslinking thermoplastic elastomer in the asphalt. The composition is then aged as a liquid for 12 to 48 hours to increase the SHRP high temperature grade.
