Abstract
Improved sealant compositions and processes for producing sealant are described. The processes include contacting in a reactor under reaction conditions a polymer containing at least one vinyl, acrylate, or methacrylate monomer and at least one silane comonomer, at least one polymer capping agent, a catalyst and a reactive diluent. Sealant compositions are also described. The compositions include a polymer containing at least one vinyl, acrylate or methacrylate monomer and at least one silane comonomer, at least one silane component, a catalyst and a reactive diluent.
Claims37
A process for producing a sealant comprising the step of:
- contacting in a reactor under reaction conditions
- a polymer comprising at least one vinyl, acrylate, or methacrylate monomer and at least one silane comonomer,
- at least one polymer capping agent,
- a catalyst, and
- a reactive diluent, wherein the reactive diluent is an alkylene carbonate.
A sealant composition comprising:
- a polymer comprising at least one vinyl, acrylate or methacrylate monomer and at least one silane comonomer,
- at least one polymer capping agent,
- a catalyst, and
- a byproduct of a reactive diluent, wherein the reactive diluent is an alkylene carbonate.
