Abstract
A method of forming polymerization auxiliaries for a polymerization process may include combining an antifouling agent with a killer agent to form an auxiliary composition; and contacting the auxiliary composition with an alkylaluminum. An antifouling complex may be produced by combining an antifouling agent with a killer agent to form an auxiliary composition; and contacting the auxiliary composition with an alkylaluminum.
Claims20
A method of forming polymerization auxiliaries for a polymerization process, comprising:
- combining an antifouling agent comprising a polyglycerol ester with a killer agent to form an auxiliary composition that is a homogenous single-phase solution;
- and
- contacting the auxiliary composition with an alkylaluminum;
- wherein the contacting occurs prior to a degassing step or during degassing.
A method of forming polymerization auxiliaries for a polymerization process, comprising:
- combining an antifouling agent with a killer agent to form an auxiliary composition that is a homogenous single-phase solution;
- and
- contacting the auxiliary composition with an alkylaluminum;
- wherein the contacting occurs prior to a degassing step or during degassing and wherein the auxiliary composition is injected into a degassing system.
A method of forming polymerization auxiliaries for a polymerization process, comprising:
- combining an antifouling agent with a killer agent to form an auxiliary composition that is a homogenous single-phase solution;
- and
- contacting the auxiliary composition with an alkylaluminum, wherein the antifouling agent and the alkyl aluminum react to form an antifouling complex that comprises a polyglycerol ester, aluminum alkyls and aluminum stearates;
- wherein the contacting occurs prior to a degassing step or during degassing.
