Claims
- 1. A linear telechelic diene polymer having hydrazide terminal groups and a molecular weight of about 300-20,000, the polymer chain thereof consisting of a homopolymer of a non-cyclic conjugated 1,3-diene having 4 to 6 carbon atoms or a copolymer of a non-cyclic conjugated diene having 4 to 6 carbon atoms and an ethylenically unsaturated compound selected from the group consisting of styrene, vinyl toluene, alkoxy styrene having up to 3 carbon atoms in the alkoxy moiety, halogenated styrene, nitriles of acrylic and methacrylic acid and alkyl esters of acrylic and methacrylic acid having from 1 to 6 carbon atoms in the alkyl moiety, said copolymer containing said ethylenically unsaturated compound in an amount of up to 50 mol % and the terminal groups of said linear telechelic diene polymer being of the formula ##STR10## where R is alkyl having 1 to 4 carbon atoms, R' is hydrogen or alkyl having 1 to 4 carbon atoms and R" is hydrogen, alkyl having 1 to 4 carbon atoms or phenyl.
- 2. A linear telechelic diene polymer of claim 1 having the formula ##STR11## ps wherein R is alkyl having 1 to 4 carbon atoms, R' is hydrogen or alkyl having 1 to 4 carbon atoms, R" is hydrogen, alkyl having 1 to 4 carbon atoms or a phenyl radical, R.sub.3 and R.sub.4 independently are hydrogen, methyl or chlorine and n is a number from 1 to 370.
- 3. A linear telechelic diene polymer of claim 1 having the formula ##STR12## wherein R is alkyl having 1 to 4 carbon atoms, R' is hydrogen or alkyl having 1 to 4 carbon atoms, R" is hydrogen or alkyl having 1 to 4 carbon atoms, Q is a polymer chain made up of radicals Q.sub.1 and Q.sub.2 with a molar ratio of Q.sub.1 :Q.sub.2 of 10:1 to 1:1 with any distribution of Q.sub.1 and Q.sub.2 within the polymer chain, Q.sub.1 being ##STR13## Q.sub.2 being ##STR14## the number of connected radicals Q.sub.1 and Q.sub.2 being from 2 to about 370 and R.sub.3 and R.sub.4 independently are hydrogen, methyl or chlorine.
- 4. A linear telechelic diene polymer of claim 1 having the formula ##STR15## wherein R is alkyl having 1 to 4 carbon atoms, R' is hydrogen or alkyl having 1 to 4 carbon atoms, R' is hydrogen or alkyl having 1 to 4 carbon atoms, R" is hydrogen of alkyl having 1 to 4 carbon atoms, R.sub.3 and R.sub.4 independently are hydrogen, methyl or chlorine, m is an integer of from 1 to 250 and wherein the monomer units within the square brackets may have any distribution.
- 5. A linear telechelic diene polymer of claim 1 wherein said non-cyclic conjugated 1,3-diene is selected from the group consisting of butadiene, isoprene, chloroprene, and 2,3-dimethyl-butadiene-(1,3).
