Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
94 words
A moldable composition comprising a thermosetting polyester resin and a thermoplastic resin, said thermoplastic resin comprising the reaction product of a polyol and a dimer acid or a trimer acid, said dimer acid being an aliphatic, dibasic, long chain acid having at least 36 carbon atoms in said chain and having two alkyl side chains and having at least one ethylenic bond, said trimer acid being an aliphatic, tribasic, long chain acid having at least 54 carbon atoms in said chain and at least three alkyl side chains and at least one ethylenic bond.
Claim 2
Dependent Claim
94 words
A moldable composition comprising a thermosetting polyester resin and a thermoplastic resin, said thermoplastic resin comprising the reaction product of a polyol and a dimer acid or a trimer acid, said dimer acid being an aliphatic, dibasic, long chain acid having at least 36 carbon atoms in said chain and having two alkyl side chains and having at least one ethylenic bond, said trimer acid being an aliphatic, tribasic, long chain acid having at least 54 carbon atoms in said chain and at least three alkyl side chains and at least one ethylenic bond.
Claim 3
Dependent Claim
36 words

Claim 5
Dependent Claim
46 words
The moldable composition of claim 3 in which said mixture of acids is reacted with said polyol in an amount within the range of from about 2 to about 5 parts by weight of said mixture of acids to 1 part by weight of said polyol.
Claim 6
Dependent Claim
32 words
The moldable composition of claim 1 in which said thermoplastic resin is the reaction product of said polyol, said dimer acid or said trimer acid and a mixture of glycols and oligomers.
Claim 7
Dependent Claim
35 words

Dependent Claim
61 words
The moldable composition of claim 6 in which said mixture of acids is reacted with said polyol and said mixture of glycols and oligomers in an amount within the range of from about 1.5 to about 5 parts by weight of said mixture of acis to 1 part by weight of the total weight of said polyol and said glycol-oligomer mixture.
Claim 9
Independent Claim
102 words
A method of improving the molding characteristics of a molding compound comprising a thermosetting polyester which comprises incorporating in said molding compound a thermoplastic resin comprising the reaction product of a polyol and a dimer acid or a trimer acid, said dimer acid being an aliphatic, dibasic, long chain acid having at least 36 carbon atoms in said chain and two alkyl side chains and at least one ethylenic bond, said trimer acid being an aliphatic, tribasic, long chain acid having at least 54 carbon atoms in said chain and at least three alkyl side chains and at least one ethylenic bond.
Claim 10
Independent Claim
102 words
A method of improving the molding characteristics of a molding compound comprising a thermosetting polyester which comprises incorporating in said molding compound a thermoplastic resin comprising the reaction product of a polyol and a dimer acid or a trimer acid, said dimer acid being an aliphatic, dibasic, long chain acid having at least 36 carbon atoms in said chain and two alkyl side chains and at least one ethylenic bond, said trimer acid being an aliphatic, tribasic, long chain acid having at least 54 carbon atoms in said chain and at least three alkyl side chains and at least one ethylenic bond.
Claim 11
Dependent Claim
