The Board therefore exceptionally admitted the late filed 220 request into the ezcorez. The catalyst can be chosen from any suitable Friedel-Crafts catalyst, such as aluminum trichloride, aluminum bromide, aluminum fluoride, titanium tri and tetrachloride, tin tetrachloride, boron trifluoride, or 2s solutions, slurries or complexes thereof. The Respondents requested that the appeal be dismissed. These resins have an improved adhesive performance in hot melt pressure sensitive adhesive compositions.

The use of a hot melt pressure sensitive adhesive composition as defined in any of claims 6 to 14 for preparing an adhesive tape or an adhesive label.

Mention of the grant of European patent No. Again the resulting resin caused a lower melt viscosity in the hot melt pressure sensitive composition together with excellent tack and shear properties see example 2. It was also observed that such resins had a better compatibility escorz aromatic solvents, as could be seen by the lower Escorsz cloud point. In the oral proceedings the Appellant conceded that D29 was available to the public inie before the date of the second priority, and that this document was therefore citable prior art.

Typical polymerization conditions for the above mentioned resin are given below. Hot melt pressure sensitive adhesive composition useful for contact coating on heat sensitive substrates.

In particular the deficiencies were as follows: The Opposition Division held that the problem to be solved was the provision of low viscosity HMPSA hot melt pressure sensitive adhesive compositions which can be applied to substrates as a melt using high speed coating equipment.

All three resins are within the scope of this invention as defined by the appending claims and all are based on a feed containing cyclodiolefinic components. Some applications are described using resins with softening points between 70 and 85 C. The solvent used during the polymerization is pure toluene 22003 plant recycled toluene. D29, which was made available to the public before the date of the second priority 28 Novemberis therefore citable prior art.

In such a case, the adhesive composition may additionally include some polystyrene-polyisoprene diblocks. Examples of diolefins are cis and trans-piperylene 1,3-pentadiene1,4-pentadiene, isoprene, 1,3-hexadiene esxorez 1,4-hexadiene.

The catalyst was simultaneously added and the mixture was 22033 from the bottom of the reactor to the catalyst inlet point. Because the amount of cyclic components in the feed is also influencing the final amount of cyclic structures in the resin and thus the ultimate melt viscosity of a hot melt pressure sensitive composition, a preferred composition is given as well.

The claimed solution to this problem by the choice of the specific coating temperature range and coating speed was obvious because these features were already foreshadowed in D The hot escoorez pressure sensitive adhesive composition according to claim 4 which further includes an extender oil.

The main request is therefore not allowable. Admissibility of the Requests 2. Examples of cycloolefins are cyclopentene and cyclohexene. Therefore D29, which was made available to the public before the second priority date of 28 Novemberbecame citable prior art.

Claim 1 of auxiliary request 4 corresponds to Claim 1 of auxiliary request 3, except for the following modifications: The abbreviations and trade names used in the following are explained in the Experimental Section below. The method according to claim 22003 or 17 characterized that the increase of cyclic structures is observed by measuring the hot melt viscosity of the petroleum-based aliphatic resin or of a hot melt pressure sensitive adhesive resin composition wherein said resin is used.

Enclosed were several sets of claims as bases for a new main request and auxiliary requests 1 to 2230 Dechlorination method and apparatus suitable for C5 petroleum resin hydrogenation process. Consistently with the statement of Mr. The peel strength is measured by a PSTC-1 test. Boards of Appeal Contact us using an online form.
