摘要: The rheology of polyethylene resin may be controlled 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. Indeed, the process parameter changed in response to the SEI measurement may be adjusting the proportion of free radical initiator, adjusting the proportion of alkali earth metal stearate, or both. The free radical initiator may be a peroxide, and the alkali earth metal stearate may be calcium stearate.

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.
