US Patent:

48989258, Feb 6, 1990

Filed:

Sep 12, 1988

Appl. No.:

7/243381

Inventors:

George L. Collins - Maplewood NJ
Kurt F. Wissbrun - Short Hills NJ
Hongkyu Kim - Madison NJ

Assignee:

Hoechst Celanese Corporation - Somerville NJ

International Classification:

C08G 210

US Classification:

528230

Abstract:

There are provided new elastomeric copolymers of about 15 to 45 mol %, preferably about 25 to 35 mol % trioxane, about 55 to 85 mol %, preferably about 65 to 75 mol % of 1,3-dioxolane, said mol percents based on the total of trioxane and 1,3-dioxolane, and about 0. 005 to 0. 15 wt. %, preferably about 0. 05 to 0. 12 wt. % of 1,4-butanediol diglycidyl ether or butadiene diepoxide as a bifunctional monomer, based on the total weight of copolymer. The elastomeric copolymers may be prepared by mixing said monomers in a substantially dry state and under an inert atmosphere with a cationic polymerization catalyst, e. g, p-nitrobenzenediazonium tetrafluoroborate. The elastomeric copolymers have a strong interaction with moldable, crystalline acetal polymers comprising at least 85 mol % of polymerized oxymethylene units and may be used as a blending agent with such crystalline acetal polymers or as a bonding agent to improve the adhesiveness of the crystalline acetal polymer to other materials.

C08G 210

US Classification:

428414

Abstract:

There are provided new articles comprising elements having surfaces bonded together with a bonding resin which is an elastomeric copolymer of about 15 to 45 mol %, preferably about 25 to 35 mol % trioxane, about 55 to 85 mol %, preferably about 65 to 75 mol % of 1,3-dioxolane, said mol percents based on the total of trioxane and 1,3-dioxolane, and about 0. 005 to 0. 15 wt. %, preferably about 0. 05 to 0. 12 wt. % of 1,4-butanediol diglycidyl ether or butadiene diepoxide as a bifunctional monomer, based on the total weight of copolymer. Preferably, at least one of said surfaces, and more preferably at least two of said surfaces bonded to each other are of a crystalline acetal polymer comprising at least 85 mol % of polymerized oxymethylene units.
