Abstract
The present invention is directed to a method of forming a polymer composition having quaternary alkane units and aromatic hydrocarbon units. The aromatic hydrocarbon units have substituents of the general formula R1SiR2R3R4, wherein R1 is optional and is a hydrocarbon or ether linking the silicon and the aromatic hydrocarbon, and R2, R3, and R4 are one or more of hydrogen, alkyl, and alkoxy, with the provision that no more than two may be hydrogen or alkyl.
Claims19
A method for forming a polymer comprising initiating a polymerization of tertiary alkene monomers and vinyl aromatic hydrocarbon monomers, said vinyl aromatic hydrocarbon monomers having substituents of the formula R1SiR2R3R4, wherein R1 is optional and is a hydrocarbon or ether linking the silicon and said vinyl aromatic, and R2, R3, and R4 are one or more of hydrogen, alkyl, and alkoxy, with the proviso that no more than two may be hydrogen or alkyl.
A method for forming a building sealant comprising:
- initiating cationic polymerization of tertiary alkene monomer units and vinyl aromatic hydrocarbon monomer units, said vinyl aromatic hydrocarbon monomer units having substituents of the formula R1SiR2R3R4, wherein R1 is optional and is a hydrocarbon or ether linking the silicon and said vinyl aromatic, and R2, R3, and R4 are one or more of hydrogen, alkyl, and alkoxy, with the proviso that no more than two may be hydrogen or alkyl, to form a sealant polymer, and combining said sealant polymer with a hardener.
A sealant polymer composition formed by:
- initiating a cationic polymerization of tertiary alkene monomer units and vinyl aromatic hydrocarbon monomer units, said vinyl aromatic hydrocarbon monomer units having substituents of the general formula R1SiR2R3R4, wherein R1 is optional and is a hydrocarbon or ether linking the silicon and said vinyl aromatic, and R2, R3, and R4 are one or more of hydrogen, alkyl, and alkoxy, with the proviso that no more than two may be hydrogen or alkyl.
