Abstract
Abstract The preparation of interpolymers of ethylene by interpolymerization of ethylene, an unsaturated organo silane and a monoolefin and with or without a polyene in the presence of a Ziegler type catalyst, particularly to produce uniquely modified polymers from the post-reaction between nucleophiles and the hydrolyzable groups that remain attached to the silicon atom in the interpolymer.

Claim 14
Independent Claim
219 words
The method which comprises the interpolymerization in solvent solution in the presence of a Ziegler type catalyst of an ethylenically unsaturated organo silane having the general formula RnSiX4 n in which X is a highly hydrolyzable group other than an oxygen containing group, R is a group selected from the group consisting of hydrogen, alkyl, aryl, alkaryl, arylalkyl, cyclic or heterocyclic group in which at least one of the R groups contains an unsaturated carbon to carbon linkage, and olefinic monomers selected from the group consisting of (1) ethylene, (2) a monoolefin having from three to 20 carbon atoms and (3) a polyene, but in which at least ethylene is present as a monomer, and in which where both ethylene and the monoolefin are present the ethylene and monoolefin are present in the mole ratio of 20-95 moles ethylene to 80-5 moles monoolefin, and when the polyene is present the polyene is present in an amount within the range of 0.1 to 10 mole percent and the unsaturated organo silane is present in an amount within the range of 0.1 to 10 percent by weight, and then reacting the product to effect substitution of a nucleophilic group for at least one of the hydrolyzable X groups which remains attached to the silicon atoms in the interpolymer that is formed.
Claim 15
Dependent Claim
73 words

Claim 16
Dependent Claim
32 words
The method as claimed in claim 15 in which the unsaturated organosilane is selected from the group consisting of the vinyl, allyl, crotyl, divinyl, diallyl, dicrotyl and styryl trihalo and dihalo silanes.

Dependent Claim
20 words
The method as claimed in claim 15 in which the unsaturated group of the organosilane compound is a norbornenyl group.
Claim 18
Dependent Claim
17 words

Claim 21
Dependent Claim
25 words
The method as claimed in claim 21 in which the alcohol is an unsaturated alcohol which increases the amount of unsaturation in the formed interpolymer.
Claim 22
Dependent Claim
15 words

Claim 23
Dependent Claim
40 words
The method as claimed in claim 15 in which the post-reaction comprises adding a secondary or tertiary alcohol to the solution following polymerization to kill the catalyst while still leaving hydrolyzable groups attached to the silicon atom in the interpolymer.
Claim 24
Dependent Claim
35 words
The method as claimed in claim 15 in which the interpolymer is reacted with a dyestuff having free amino or hydroxyl groups to substitute the dye group for hydrolyzable groups attached to the silicon atoms.
Claim 25
Dependent Claim
43 words
The method as claimed in claim 15 which includes the step of killing the catalyst without removal of hydrolyzable groups attached to the silicon atom of the formed interpolymer before reacting the interpolymer for replacement of hydrolyzable groups attached to the silicon atom.
