摘要:
The invention provides a composition which increases the impact strength and lowers the viscosity of melt processed plastics resins. In particular the invention relates to an impact modifier composition comprising at least one impact modifier and at least one mineral oil and optionally up to 50% by weight of at least one plastics resin. Methods of making such impact modifier compositions are disclosed, together with a general process for combining at least one oil with at least one impact modifier during the impact modifier manufacturing process.
摘要:
A multimodal polymer particle composition containing two or more populations of polymer particles having a total rubbery weight fraction of less than 90 weight percent is provided. Also disclosed is a process for preparing multimodal polymer particle compositions that can be dried to a powder. Multimodal polymer particle dispersions are disclosed for preparing impact modifiers that can be dried to a powder. Also provided are polymeric compositions having a matrix resin component and impact modifiers prepared from multimodal polymer particles.
