A semi-crystalline polyester comprising a repeat unit of the formula:wherein A is an aliphatic, aromatic, or heterocyclic group; Ris selected from the group consisting of 1,4-butanediol residue and 1,4-cyclohexanedimethanol residue; Ris neopentanediol residue; m is between 50 and 99 inclusive; n is between 1 and 50 inclusive; x is between 1 and 200 inclusive; and wherein said semi-crystalline polyester exhibits a minimum crystallization half-time of about 0.3 minutes or greater, or about 0.5 minutes or greater or about 0.6 minutes or greater or about 0.7 minutes or greater is described. The polyesters of the present invention may in various embodiments demonstrate one or more desirable performance characteristics and accordingly are particularly useful in applications and utilities wherein those high levels of performance for such characteristics are required. A process for forming the semi-crystalline polyester is also disclosed.

Abstract:
The invention provides (meth)acrylic oligomers prepared from C1-C20 alkyl and C5-C20 cycloalkyl (meth)acrylates, wherein said oligomers have a Mn of about 300 g/mole to about 3,000 g/mole; a Mw of about 700 g/mole to about 6,000 g/mole; a Mz of about 900 g/mole to about 10,000 g/mole. The oligomers may have a Yellowness Index, according to ASTM E313 of less than 2. The oligomers of the invention are useful as tackifiers in adhesive compositions, but also are believed to be useful also in general polymer modification as plasticizers, leveling agents, viscosity reducers (i.e., rheology modifiers), and for increasing solids content in solvent-borne applications of all types with little detrimental impact on viscosity. The invention also provides adhesive compositions and laminate articles coated on at least one side with the adhesive compositions of the invention.
