Patent Number Title Of Patent Date Issued
7202310 Polymers, processes for producing the same, and curable compositions produced therefrom April 10, 2007
An alkenyl- or crosslinkable silyl-terminated vinyl polymer is provided. Such a functional group is introduced into its terminus at a high ratio, not via sulfur atoms. Those polymers can be prepared by polymerizing a vinyl monomer for obtaining a halogen-terminated vinyl polymer, and the
7129294 Functional groups-terminated vinyl polymers October 31, 2006
A vinyl polymer which has at least one terminal functional group per molecule and has a ratio of weight average molecular weight to number average molecular weight of less than 1.8 as determined by gel permeation chromatography, said terminal functional group being a crosslinking silyl
6667369 Processes for preparing (meth) acrylic polymers having functional groups at the chain ends December 23, 2003
(Meth)acrylic polymers having alkenyl or curable silyl groups at the chain ends in high functionality ratios are prepared by a process which comprises (i) preparing a (meth)acrylic polymer having halogen atoms at the chain ends, using an organohalogenated compound or a halosulfonyl c
6441101 Processes for preparing (METH) acrylic polymers having functional groups at the chain ends August 27, 2002
(Meth)acrylic polymers having alkenyl or curable silyl groups at the chain ends in high functionality ratios are prepared by a process which comprises (i) preparing a (meth)acrylic polymer having halogen atoms at the chain ends, using an organohalogenated compound or a halosulfonyl c

6291612 Process for preparing vinyl polymer September 18, 2001
A vinyl polymer having a controlled molecular weight and narrow molecular weight distribution is prepared by polymerizing a vinyl monomer using an organic halide polymerization initiator in the presence of a cuprous compound catalyst in a solvent containing an organic compound having a
6274688 Functional groups-terminated vinyl polymers August 14, 2001
A vinyl polymer which has at least one terminal functional group per molecule and has a ratio of weight average molecular weight to number average molecular weight of less than 1.8 as determined by gel permeation chromatography, said terminal functional group being a crosslinking silyl
6194516 Method for producing hydroxyl-terminated (meth) acrylic polymer February 27, 2001
A method for producing a hydroxyl-terminated (meth) acrylic polymer which comprises converting a halogen atom in a terminal structure of the general formula (1)wherein R.sup.1 is hydrogen or methyl, R.sup.2 is alkyl containing 1 to 20 carbon atoms, aryl containing 6 to 20 carbon atoms or
