Abstract
Abstract A hardenable molding composition containing a sulfochlorinated polyolefin or sulfochlorinated olefin copolymer and a crosslinking agent, said crosslinking agent being an organic derivative or mixture of organic derivatives of titanic acid, e.g., the reaction product of a titanic acid ester with a chelating agent such as a β-dicarbonyl compound, an acetic acid ester or a polyhydroxy compound. Molding compositions of the invention can contain conventional additives, fillers, solvents, plasticizers, flameproofing agents, thixotropic agents and/or adhesivizing agents and the like.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
53 words
A hardenable molding composition comprising a sulfochlorinated polyolefin or sulfochlorinated olefin copolymer and a crosslinking agent, said crosslinking agent being a titanium acid ester, a titanium acylate or a titanium chelate, which titanium chelate is the reaction product of a titanic acid ester with a chelating agent or a mixture of chelating agents.
Claim 2
Dependent Claim
53 words
A hardenable molding composition comprising a sulfochlorinated polyolefin or sulfochlorinated olefin copolymer and a crosslinking agent, said crosslinking agent being a titanium acid ester, a titanium acylate or a titanium chelate, which titanium chelate is the reaction product of a titanic acid ester with a chelating agent or a mixture of chelating agents.
Claim 3
Dependent Claim
67 words
A hardenable molding composition according to claim 1 wherein the crosslinking agent is a titanic acid ester of the formula Ti(YR) 4 or TI(YR) 3 -Y-Ti(YR) 2n -Y-Ti(YR) 3 wherein Y represents oxygen or sulfur, n represents a number between 0 and 20 and R in each case independently represents a cycloalkyl, aralkyl, alkylaryl, aryl or alkyl group which can contain oxygen or sulfur in the chain.

Dependent Claim
16 words
A hardenable molding composition according to claim 2 wherein the crosslinking agent is a titanium chelate.
Claim 5
Dependent Claim
24 words
A hardenable molding composition according to claim 3 wherein the chelating agent is a β-dicarbonyl compound, an acetic acid ester or a polyhydroxy compound.
Claim 6
Dependent Claim
20 words
A hardenable molding composition according to claim 4 wherein the chelating agent is an alkanolamine or an acetic acid ester.
Claim 7
Dependent Claim
24 words
A hardenable molding composition according to claim 5 wherein the chelating agent is an alkanolamine selected from the group consisting of triethanolamine and N-methyldiethanolamine.

Claim 10
Dependent Claim
41 words
A hardenable molding composition according to claim 1 wherein said crosslinking agent is a titanium chelate obtained by reaction of a titanic acid ester with sufficient chelating agent to effect splitting off of all alkoxy groups of the titanic acid ester.
Claim 11
Dependent Claim
34 words
A hardenable molding composition according to claim 1 wherein the crosslinking agent is present in an amount of 2 to 50 weight percent based upon the weight of sulfochlorinated polyolefin or sulfochlorinated olefin copolymer.
