The invention relates to a controlled polymerization method for producing ABA-triblock copolymers on the basis of (meth)acrylate with A-blocks which have a narrow, monomodal molecular weight distribution and a B-block which has a bimodal molecular weight distribution, and to the use thereof as binders in glues and sealing materials.

Method for producing ABA-triblock copolymers with a bimodal B-block

The invention relates to a controlled polymerization method for producing ABA-triblock copolymers on the basis of (meth)acrylate with A-blocks having a narrow, monomodal molecular weight distribution, and a B-block having a wide, monomodal molecular weight distribution. The invention further relates to the use thereof as binders in glues or sealing compounds.

Method for producing ABA-triblock copolymers with a widely distributed B-block

The invention relates to a controlled polymerization process for preparing (meth)acrylate-based AB diblock copolymers with a B block which has a narrow monomodal molecular weight distribution, and an A block which has a broad monomodal molecular weight distribution, and to the use thereof, for example, as a binder in adhesives or sealants.

Process for preparing AB diblock copolymers with a broadly distributed A block

The invention relates to a controlled polymerization process for preparing (meth)acrylate-based AB diblock copolymers with a B block which has a narrow monomodal molecular weight distribution, and an A block which has a broad bimodal molecular weight distribution, and to the use thereof, for example, as a binder in adhesives or sealants.

Process for preparing AB diblock copolymers with a bimodally distributed A block

Melt adhesive containing 5 to 40 wt.-% of at least one ethylene-based copolymer and at least one Cto C-&#x3b1;-olefin obtained through metallocene-catalyzed polymerization, 10 to 65 wt.-% of at least one tackifying resin, 0 to 35 wt.-% of a plasticizer, 0.01 to 30 wt.-% additives and additional ingredients selected from stabilizers, adhesion promoters, fillers or pigments, waxes and/or other polymers, wherein the total should amount to 100%, characterized in that copolymer A is a block copolymer that exhibits a substantially even elastic behavior in the range of 0&#xb0; C. to 25&#xb0; C., measured as the ratio of the storage modulus E' according to (E&#x2032;&#x2212;E&#x2032;)/E&#x2032;&#x3c;1.5.

Melt adhesive based on metallocene catalyzed olefin-&#x3b1;-olefin copolymers

A hot-melt adhesive for resealable packaging, containing 30 to 90 wt. % of at least one copolymer based on ethylene and/or propylene together with Cto C-&#x3b1;-olefins, which is obtainable by metallocene-catalyzed polymerization, with a melt index of 5 to 100 g/10 min (DIN ISO 1133), 5 to 50 wt. % of tackifier resins with a softening point of 80 to 140&#xb0; C., 0 to 15 wt. % of waxes with a melting point of 120 to 170&#xb0; C., 0.1 to 20 wt. % of additives and auxiliaries, the adhesive having a viscosity of 25,000 mPa&#xb7;s to 250,000 mPa&#xb7;s, measured at a temperature of 170 to 190&#xb0; C.

Coextrudable hot-melt adhesive

The invention relates to a process for preparing CABAC or ACBCA pentablock copolymers based on (meth)acrylate with an OH functionalization of the A blocks.
